Merge is made with the name of the PR author/commiter

Belonging to an organisation using Gitea, I submitted a PR to one of the repositories.

When the PR got merged, it said I did the merge, whil actually someone else (admin) did it.

Are there knobs to turn to avoid that impersonation behaviour? I find the fact this is even possible worrying.
IMHO, while admins should be able to bypass some rules (like reviews and such), they should never make actions which are not authenticated by them.

isn’t’ this more a matter of admin doing the merge and iirc there is a PR open for this
