Thank you for sharing this solution!
To be honest, I’ve moved away from the Amazon line of products for home automation and invested a bit around the Google Assistant. So, instead of the Android tab I had in my living room, now I have replaced it with a 10 inch Lenovo Smart Display. So, while that does not let me do any of the custmamisations that a standard tab would allow, it works seamlessly with the rest of the equipment I have. Few months down the line, I’d most probably replace the door bell with one that fits in better with my existing eco system.
Again, thanks for the interest shown by all on this thread and hope the conversation will come in handy for another person that comes looking for the same thing.
