Door view cam not alerting through Alexa. UK

Hi, need some advice please?! Just bought a door view cam and I cannot get it to alert me through my Alexa devices. I have echo show 5’s / 8’s and a dot . Doesn’t work through any of them. I am registered on the same email through Amazon and Ring. I have enabled the skill, switched on enable doorbell announcements. I’ve tried setting up a routine, putting it on a group and assigning all my echoes as speakers. These are all the tips I could find through google but still, no joy. It’s pretty much useless to me without this feature so if anyone has any suggestions please?? Thanks in advance.
