Get-PnPSearchCrawlLog on userprofiles returns no result

[Kris3D]

When I try the following command with a user who has rights on the crawl logs I get no result:
Get-PnPSearchCrawlLog -RowLimit 10 -ContentSource UserProfiles

I am connected to the https://mydomain.sharepoint.com SPS while performing this command.

Does this mean userprofiles are not indexed in my sps? I also habe problems with the pnp-modern-search on localpeoplesearch.
That's the reason I examined the log files.

What can be done to remedy this?
