Powershell Invoke-RestMethod Paging - powershell

Question

I am trying to get a list of all users from our Azure B2C tenant.
With some help from the internet I was able to create the powershell script below. But the result is incomplete it only shows 100 users. After searching around I found I should probably do something with Paging but I can't get it to work.
Can someone help me to modify the script below to return all users?
# Application (client) ID, tenant Name and secret
$clientId = "**********"
$tenantName = "*********"
$clientSecret = "************"
$resource = "https://graph.microsoft.com/"
$ReqTokenBody = #{
Grant_Type = "client_credentials"
Scope = "https://graph.microsoft.com/.default"
client_Id = $clientID
Client_Secret = $clientSecret
}
$TokenResponse = Invoke-RestMethod -Uri "https://login.microsoftonline.com/$TenantName/oauth2/v2.0/token" -Method POST -Body $ReqTokenBody
$Url = "https://graph.microsoft.com/beta/users?$select=displayName"
$Data = Invoke-RestMethod -Headers #{Authorization = "Bearer $($Tokenresponse.access_token)"} -Uri $Url -Method Get
$Users = ($Data |select-object Value).Value
$Users | Format-Table DisplayName -AutoSize

Answer 1

Ok i got it to work in Powershell Core (Version 7.1.3).
This is the code I ended up using.
# Application (client) ID, tenant Name and secret
$clientId = "**************"
$tenantName = "***************"
$clientSecret = "******************"
$resource = "https://graph.microsoft.com/"
$ReqTokenBody = #{
Grant_Type = "client_credentials"
Scope = "https://graph.microsoft.com/.default"
client_Id = $clientID
Client_Secret = $clientSecret
}
$TokenResponse = Invoke-RestMethod -Uri "https://login.microsoftonline.com/$TenantName/oauth2/v2.0/token" -Method POST -Body $ReqTokenBody
$Url = "https://graph.microsoft.com/beta/users?$select=displayName"
$UserResponse = Invoke-RestMethod -Headers #{Authorization = "Bearer $($Tokenresponse.access_token)"} -Uri $Url -Method Get -Verbose
$CloudUser = $UserResponse.Value
$UserNextLink = $UserResponse."#odata.nextLink"
while ($UserNextLink -ne $null) {
$UserResponse = (Invoke-RestMethod -Headers #{Authorization = "Bearer $($Tokenresponse.access_token)"} -Uri $UserNextLink -Method Get -Verbose)
$UserNextLink = $UserResponse."#odata.nextLink"
$CloudUser += $UserResponse.value
}
$CloudUser | Format-Table DisplayName -AutoSize

Most of the last 8 lines (or so) are repeated. You can factor it out like this:
$Url = "https://graph.microsoft.com/beta/users?$select=displayName"
$headers = #{Authorization = "Bearer $($Tokenresponse.access_token)"}
$CloudUser = #()
do {
$UserResponse = Invoke-RestMethod -Headers $headers -Uri $Url -Method Get -Verbose
$CloudUser += $UserResponse.Value
$Url = $UserResponse."#odata.nextLink"
} while ($Url)
Also, why not use the Graph PowerShell module for this? https://learn.microsoft.com/en-us/powershell/microsoftgraph
