Any ideas for integrating Ezviz DB1C doorbell with Home Assistant?

I have an Ezviz DB1C smart video doorbell with an Ezviz wireless chime. The wireless chime is far too quiet, so we often don’t hear it (we have a 3-storey house).

I was thinking about getting a separate hard-wired chime for the DB1C, and then wondered whether it would be possible to integrate it with my Home Assistant system - e.g. for doorbell presses to trigger a HA script which plays a chime on the media players around the house.

Does anyone have any idea how this might be done, and/or can recommend a decent chime and transformer for use with the DB1C?
