You can accomplish the same thing without any custom software. I have a Reolink PoE doorbell, using Frigate and Home Assistant like OP, and the Advanced Camera Card from HACS.

Ringing the doorbell sends a notification with a snapshot and a link that takes me to a tab in the dashboard with the advanced camera card. I can then use it to speak if I so desire, and I've also set up buttons on that page for the "quick reply" messages.
