google compute engine - GCP open firewall only to cloud shell

Question

Is there a way in GCP to explicitly allow firewall rule only from cloud shell. All the GCP demos and videos add the rule allow 22 to 0.0.0.0/0 to ssh to the instance from cloud shell.

However is there a way we could restrict the access only from cloud shell - either using cloud shell's IP range or service account ?
