Send access requests to SP group (no email adress) instead of site owner

Hi,

we have a SharePoint Online Document library containing some subfolders with special permissions.

Now the permission can only be granted by the site owner which means a lot of research work per request. Until now you can only add specific email adresses to send the requests.

Is it possible somehow to enter a SP group name and NOT send the requests to the site owner?

This has to be possible for each subfolder with special permissions.

Greetings
