getting permission denied when i "ls" into mounted gcp bucket

Question

using this bash command to mount the bucket.

mkdir /tmp/gcpbucketname-full && gcsfuse --implicit-dirs gcpbucketname /tmp/gcpbucketname-full/

the bucket mounts successfully -

Yet I get permission denied when running ls /tmp/ml-9a0d-phi-shared-aif-us-p-full/

ls: reading directory '/tmp/gcpbucketname-full/': Permission denied

Is there a permissions missing?
