Add "members of the groups" to a site

Hi.

Running a site with one parent site and 8 subsites. Each subsite has its own group in the AD, synced and all working fine.

I would like to add a webpart, or list with "members of the group" so all users can see all members in the side of the page. Is that possible.

All users are in groups in the SPO, but is it possible to add a list, and point to the group? Would be fancy if a user is deleted, he/she is deleted from the list.

Thanks in advance:)
