Bug summary

I am using Prefect v3.4.8.
When I create a docker work pool directly by starting a docker worker (with --type):
prefect worker start --pool=docker-work-pool --type=docker
I cannot see the block of DockerRegistryCredentials (Optional) in this case. I need to delete the newly created docker work pool, and create a new one, so I can add the Docker Registry Credentials from the Prefect Blocks.

When creating the docker work pool manually with the Prefect UI, we can add the Block Docker Registry Credentials:
