How to remove impossible to remove white spaces in powershell - powershell

Question

Working on a PowerShell script to basically check current available 365 Licenses and pick one to assign to a new user (I know some of it's kinda jank but it's in progress).
It outputs the data collected by Get-MsolAccountSku to an array and then selects which license by index and joins it to the tenant ID from:
(Get-MsolDomain | Where-Object {$_.isInitial}).name
But no matter what I do to remove the whitespace i.e.: using trim, using replace, using regex replaces it always keeps a space around the Name of the License so it shows like:
Redactedtenantname: FLOW_FREE
Instead of:
Redactedtenantname:FLOW_FREE
I did also look at trying to either use -f somehow to format it but I couldn't figure out how to get it to play nice.
The other idea that I think could potentially work is to export it to CSV temporarily and import from CSV to see if getting the credential from CSV would clear any weird whitespace / format.
Just wondering if anyone's run into anything similar/might know what to do.
I've altered some of the stuff here to get it to fit so if the formatting of the output is a bit weird (short of the whitespace) it might just be how I copied it across.
Also if it helps the final $sku variable I get is a System.String
#Get Tenancy name (For license assignment)
$Tenant = (Get-MsolDomain | Where-Object {$_.isInitial}).name
#Get list of licenses
$test = Get-MsolAccountSku | select -ExpandProperty AccountSkuID
#Read host for selection of license (at this time only does 1 at a time will improve on)
$selection = Read-Host "Pick an object on the list i.e 1 for the first item 2 for the second etc"
#the array starts at 0 so just subtracting from the selection to make it 1-1 i.e 1 equals one 2 equals 2 etc.
$select = $selection - 1
#this selects an object from the array based on the number selected and altered above
$license = $test | Select-Object -index $select
#Manipulating the data selected above to make it fit our needs below Splitting at the : and replacing uneccessary data
$365license = #($license -split ':')
$3651 = $365license -replace '(^\s+|\s+$)','' -replace '\s+',''
$3652 = $361 -replace "redactedtenantsname",""
$tenant1 = $tenant -replace ".onmicrosft.com",""
#Joining tenancy name to formatted license name
$presku1 = "$tenant1",":","$3652"
-join $presku1
$sku = "$presku1"
$upn = "redactedtestuserupn"
Set-msoluserlicense -userprincipalname "$upn" -addlicenses "$sku"

It looks to me like the core of your problem is that you've got a string in the format <account>:<skuId> and you want to replace the <account> part with something else.
# equivalent to
# $Tenant = (Get-MsolDomain | Where-Object {$_.isInitial}).name
$tenantDomain = "my_tenant_name.onmicrosoft.com";
$tenantName = $tenantDomain -replace ".onmicrosoft.com", "";
# e.g. "my_tenant_name"
# equivalent to
# $test = Get-MsolAccountSku | select -ExpandProperty AccountSkuID
$accountSkuIds = #(
# the unique string ID of the account/SKU combination.
# see https://learn.microsoft.com/en-us/powershell/module/msonline/get-msolaccountsku?view=azureadps-1.0#outputs
"my_other_tenant:ENTERPRISEPACK"
"my_other_tenant:AAD_BASIC"
"my_other_tenant:FLOW_FREE"
"my_other_tenant:POWER_BI_STANDARD"
);
# ask the user which item they want to use
$selectedIndex = 3;
# get the selected sku from the array, remembering that arrays are
# zero-based we we need to subtract 1 from the user's selection
$accountSkuId = $accountSkuIds[$selectedIndex - 1];
# e.g. "my_other_tenant:FLOW_FREE"
# split the string "<account>:<sku>" into the array #( "<account>", "<sku>" )
# and then take the *second* item (i.e. [1])
$skuId = #( $accountSkuId -split ":" )[1];
# e.g. "FLOW_FREE"
# convert the #( "<new_account>", "<sku>" ) into the string "<new_account>:<sku>"
$license = #( $tenantName, $skuId ) -join ":";
# e.g. "my_tenant_name:FLOW_FREE"
# call the api
$upn = "my_upn";
Set-MsolUserLicense -UserPrincipalName $upn -AddLicenses $license;
