Can we change a default cloud build service account from UI?
Hi @Sabasafdar
Welcome to the Google Cloud Community!
By default, build triggers use the Cloud Build service account to execute builds. But you can also configure a build trigger to use a different service account of your choice. You can read more in this documentation.
To learn how to grant or revoke permissions to the Cloud Build service account, check out configuring access for Cloud Build Service Account.
Let me know if it helped, thanks!
