Ring Doorbell not connecting to Bose Home Speaker 500

Hi. I have a Ring Doorbell, and an Bose Homespeaker 500 with Alexa embedded. I can get my Ring doorbell to make announcements to my native Alex devices, but i can't see my Bose speaker in the Alexa app Ring Doorbell set up step. Does anyone know how to get my doorbell ring all the way throught to my Bose? Its our main home speaker so it would make our doorbell ring much more effective! Thanks in advance. Greg
