M&S intercom dmc1 system front door intercom/door bell replaced with ring doorbell 3

I’m trying to figure out how to use a ring 3 wired doorbell in place of a m&s intercom dmc 1 front door intercom/door bell. I have seen a couple of videos on how to get both devices working together and that is nice however I’m interested in replace the m&s intercom dmc 1 front door intercom/door bell with the ring 3 doorbell. I know that I will need power in order for this to work. If anyone has any advice I could use it! Thank you in advance for your time and effort.
