To automatically remove a listener's access from a feed, you can use the Hello Audio Zapier app's "Edit Listener" step, then set their status to "Inactive". See the screenshots below.
These are all in a Hello Audio step after the trigger of your Zap. Something else has to trigger the start of the Zap to tell Hello Audio to remove the listener.
The video below uses Airtable as an example trigger to start the removal of a listener from a feed.
