filtering using gce_labels

Hi

Does anyone know how to utilise gcloud labels within ansible playbook?
IE Use Label to Identify Hosts within Google Cloud and then perform relevant actions against those hosts.

We have created gce_label using gcloud as the gce_labels function is not working.

Looking for the simplest solution. Previous solution worked with tags but no longer able to use them.

Normally you would just use hosts: XXX
So how is this done with gce_labels.

Regards,

Paul
