Hi @harshjain12 how are you going?
So hopefully, if that user is still around, they can move away from using a PAT in favor of a Private Key, or as an installation as we’ve defined here:
If the user has already left the company and has authenticated a GitHub Application with their PAT, then let us know.
Otherwise, we strongly recommend against using Personal Access Tokens with GitHub Applications and the document above should be followed.
I hope this is helpful but please let us know if you run into any issues.
