### Description

Trying to leverage Kactus for our corporate BitBucket account. I have it connected to the repository, when I try to push, it asks for either a personal GitHub or Enterprise GitHub account, since we're using a corporate BitBucket, I don't know how to proceed. None of the GitHub Enterprise fields match what I use to connect.
