Deletion of Users Linked to Looker and Cloud Source Repositories

[tanaka_masato]

When I create a LookML project, I need to connect to Git service, and now I am connecting LookML to Cloud Source Repositories in GCP.

I am currently linking LookML to GCP's Cloud Source Repositories. I am using an ssh key to connect to this link, but if the user who connected to LookML is deleted from both GCP and Looker, will the current link between LookML and Cloud Source Repositories be deleted?

Is there a way to prevent the linkage from being deleted?
Is it possible to link LookML and Cloud Source Repositories with a service account? If so, the linkage would continue unless the service account is deleted.

We would appreciate it if someone with knowledge could let us know.
Thank you in advance.
