Getting Teams meeting transcripts using Powershell with Graph API

I have set up an Enterprise App in Entra with the following API permissions:

Microsoft.Graph

OnlineMeetings.Read (Delegated)
OnlineMeetings.Read.All (Application)

User.Read.All (Application)

Admin consent has been granted for the Application types.

Below is the code snippet for getting the meetings:

$tenantId = "xxxxxx"
$clientId = "xxxxxx"
$clientSecret = "xxxxxx"
$secureSecret = ConvertTo-SecureString $clientSecret -AsPlainText -Force

$psCredential = New-Object System.Management.Automation.PSCredential ($clientId, $secureSecret)

Connect-MgGraph -TenantId $tenantId -ClientSecretCredential $psCredential -NoWelcome

$meetings = Get-MgUserOnlineMeeting -UserId "email address removed for privacy reasons" -All

Connect-MgGraph is invoked without errors. I had verified this with Get-MgContext command.

At line 10 I get this error:

Status: 404 (NotFound) ErrorCode: UnknownError

I don't know if this is means there was an error in the API call, or there were no records found (I do have Teams calls with transcripts though).

I have tried changing the last line to (without -All):

$meetings = Get-MgUserOnlineMeeting -UserId "my guid user id here"

And I get this error:

Status: 403 (Forbidden) ErrorCode: Forbidden

Adding -All parameter results in this error:

Filter expression expected - /onlineMeetings?$filter={ParameterName} eq '{id}'.

I've done some searching but I haven't found any more information nor solution for this. I hope someone can point me in the right direction.

Thanks in advance!
