Using non-public Images in PowerBI

Hi there,

i want to do a reporting for customers and part of this reporting are screenshots. I would like to have the possibility to drop Images in a folder (e.g. a Sharepoint List) and upload it. The problem here is that those are Screenshots, that other customers aren't allowed to see. I have been looking into a few options including Power Apps but i couldn't find a good solution that fits our needs. There is always to problem with authorization. Is there any possibility to deliver those Screeshots with my credentials and the customer still can see. Any inputs and ideas are appreciated.

Thanks and Kind Regards
