Code Review

The pull request aims to minimize sign-ins in VertexAI integration tests by checking if a user is already signed in before attempting to # again. This is a good optimization that can reduce the load on the authentication backend and speed up the tests. The changes look good overall, but I have a few minor suggestions.

Merge Readiness

The changes look good and address the issue of minimizing sign-ins in integration tests. I am unable to directly approve this pull request, and recommend that others review and approve this code before merging. There are no critical or high severity issues, so the pull request is ready to be merged after addressing the comments.
