Hi @Nemanja SOVIC,
Per my research, currently there is no such function to get users permission in site by graph. We can only use /sites/{sitesId}/permissions
but the resource only returns permissions granted to the Azure Apps. The api doesn't return the users in the site. Here is a similar issue with yours
This is my test result
I feel regretful to inform you that it turns out to be a by-design one. And I noticed that some end users have also proposed the same request, it is highly recommended that you can vote this ticket. Many features of our current products are designed and upgraded based on customers’ feedback. With requirements like this increase, the problem may well be released in the future. Thanks for your understanding.
