Ring-MQTT doesn't show the additional device

I am trying to integrate with my Ring Alarm devices using this plug in https://github.com/tsightler/ring-mqtt, I can see that after installation, the device addon is shown as connected:

### Ring Device Addon Connected

It appears that this addon is already connected to Ring. To force generation of a new token click the button below.

However I do not see my Ring alarm in the Configuration -> Devices, nor there is any new Discovered Integration waiting for me to add/configure.

I can verify that I did not purposely set MQTT discovery to false in my configuration.yml page and my understanding is by default this is set to true (as per: https://www.home-assistant.io/docs/mqtt/discovery/):

bash-5.0# cat configuration.yaml | grep mqtt -> gives nothing

Also if it helps I have already had a Ring integration using the official integration, should I delete that one or if there is any other things I should be checking to make the devices visible?

Thanks in advance for your help!
