Login and retrieve token via Powershell to use for Clear-PBITableRows

[MarkusSacramento86]

#Login to Power BI
$username = "name.surname@domain.se"
$password = "ENCRYPTED PASSWORD"
$cred = New-Object -TypeName System.Management.Automation.PSCredential -argumentlist $username,($password | ConvertTo-SecureString)
Login-PowerBI -Credential $cred
#Retrieve token while logged in
$PowerBIToken = Get-PowerBIAccessToken -AsString
#Trying to clear table with retrieved token
Clear-PBITableRows -authToken $PowerBIToken -DataSetId "f666h111-e553-8f64-7428-72vr74sdf57j" -TableName "RealTimeData"
#Disconnect from Power BI
Disconnect-PowerBIServiceAccount

Above code works to login my account to Power BI.
I´ve managed to store PowerBIAccessToken to a variable.
But I can´t use that variable as token when trying to clear the data.
I recieve below error:

Invoke-PBIRequest : The remote server returned an error: (403) Forbidden. - ''
