Remove 'True' and replace with object in a ForLoop in Powershell - powershell

Question

I have a small script that loops through a .csv file and applies a policy based on their location. It works fine except that when it runs its prints out "True" for every Line. How do you remove the word True and replace it with the username or something else or even nothing?
Connect-MicrosoftTeams
$userList = Import-Csv -Path "C:\Users\locationbasedpolicy1.csv"
Write-host "Logging to Microsoft Tenant to Execute Policies....." -ForegroundColor Cyan
Write-Host "There are $($userList.Count) Users in the List" -ForegroundColor Magenta
$TotalItems=$userList.Count
$CurrentItem = 1
# List Policies for Different Locations
$policyMappings = #{
USA = #{
VRP = 'VRP-USA-International';
CPP = 'CPP-USA-All-Users';
ECRP = 'ECRP-USA-All-Users';
ECP = 'ECP-USA-All-Users';
CHP = 'CHP-Global-MOH';
CIPD = 'CIDP-Global-User-Policy'
}
UK = #{
VRP = 'VRP-UK-National';
CPP = 'CPP-UK-All-Users';
ECRP = 'ECRP-UK-All-Users';
ECP = 'ECP-UK-All-Users';
CHP = 'CHP-Standard-MOH';
CIDP = 'CIDP-Block-Number'
}
}
# Loop Through the csv and identify Users Information
foreach ($Users in $userList){
Try {
$upn = $Users.UserPrincipalName
#$phone = $Users.TelephoneNumber
$Location = $Users.Location
# Search for Users Location
$policyMappings.ContainsKey($Location)
$policy = $policyMappings[$Location]
# Apply Policies to User based on their Location
Grant-CsOnlineVoiceRoutingPolicy -Identity $upn -PolicyName $policy.VRP
Grant-CSTeamsCallParkPolicy -Identity $upn -PolicyName $policy.CPP
Grant-CSTeamsEmergencyCallRoutingPolicy -Identity $upn -PolicyName $policy.ECRP
Grant-CsTeamsCallHoldPolicy -Identity $upn -PolicyName $policy.CHP
Grant-CSTeamsEmergencyCallingPolicy -Identity $upn -policyname $policy.ECP
Grant-CsCallingLineIdentity -Identity $upn -PolicyName $policy.CIDP
$PercentCompleted = [int](($CurrentItem / $TotalItems) * 100)
Write-progress -Activity "Processing User $CurrentItem of $TotalItems : $upn" -Status
"Total percent completed is: $PercentCompleted%:" -PercentComplete $PercentCompleted
$CurrentItem++
Start-Sleep -Milliseconds 3000
} Catch { Write-Host "Failed to assign policies to : $($upn)" -ForegroundColor Yellow }
}

Answer 1

Adding following changes and it worked.
$null = $($policyMappings.ContainsKey($Location))
