Focus when listening to the Hallow app

Dear Apple Community - I use the Hallow app daily on my iPad and have set up a Focus mode that disables all notifications while I'm listening. However, after 2 minutes, the Auto-Lock feature activates, which deactivates the Focus mode, though the Hallow app continues playing. This might be more of a feature request, but is there a way to set up a Focus mode so that Auto-Lock is disabled when using a specific app? I would appreciate any insights or suggestions. Thanks!
