Currently, the GSM connector only supports pulling secrets from 1 project. This means that if our secrets are spread across 100 projects, we need to create 100 connectors.

Just how multi-project OIDC support for GKE + Cloud Run was released, please add this feature to Google Secret Manager plugin too.
