Automate getting PBI logs

Hi, I want to uset powershell get-PowerBIActivityEvent to get usage logs. License is PPU.

This code works just fine with my credentials.

Is it possible to use service principal to automate this? I had no luck with it.

Error: Get-PowerBIActivityEvent : Operation returned an invalid status code 'Forbidden'

$report_date = (get-date).AddDays(-1)

$start_day = $report_date.ToString("yyyy-MM-dd") + "T00:00:00"
$end_day = $report_date.ToString("yyyy-MM-dd") + "T23:59:59"
$date = $report_date.ToString("yyyyMMdd")
$filename = "pbi_log_" + $date + ".csv"
