Ring Pro to Echo

Firstly, I'm not very technologically minded.I've bought two Ring Pro doorbells, one for front door and one for back. I've also purchased an Echo Dot to act as the chime. How do I connect them? My doorbells ring on my phone but I don't want that, I need it to ring in the house. Any help would be so much appreciated and I'm at the stage where I'm running out of hair to pull out.
