GitHub Repository Not Visible for Google Cloud Deployment

I am a collaborator on a private GitHub repository, but when I try to authenticate GitHub in Google Cloud for deployment, this repository does not appear in the list. Other repositories where I have full access are visible.

I believe this might be a permission issue. Could you please confirm:

What level of permission is required to make the repository visible in Google Cloud?
How can the repository owner grant me the necessary access for deployment?
If specific permissions are needed, please provide the steps the owner should follow to enable them.

Thanks!
