How to find out with what rights a commit was made?

SUBJ
I found a commit in my private repository that i didn’t do

can you send the link of that specific commit ?

https://github.com/evodefi/bridge-ui/commit/73b554bab9a56d39eb691c88b8b82e1c1fbaa15d

that’s 404

Because this is private repository. I heed to github administation help

how about screenshot ?

I don’t think a screenshot will help here. How can I contact github support?
