How to grant permissions to SA to access artifactory in another project

[eugene00]

Hello.

I have a project where I need to grant an SA permissions to `roles/artifactregistry.reader`.

I tried going to the other project to grant the SA the necessary permissions in the target project but the SA from the source project does not exist in the target. I think I need to use a workload identity for this role? Or how do you solve this problem?

Thanks kindly in advance for your help
