Ring Integration not loading any Device

Hey Guys,

so I have a house with many Ring Devices (sadly) and I want to integrate them into my System.
Now I have seen that there is the MQTT Addon but I wanted to try this first with the normal Integration. But this does not load any devices for some reason. I can log into my account using the integration but then nothing happens.
In the Integration overview it lists my account but then says “No devices or entities” and obviously nothing is added in entities or devices list.
In the Webinterface of Ring there are tons of devices though (base station, motion detectors, door sensors, etc.).
What am I doing wrong?
Do I have to log in as the Owner of the devices? The Account im using is just a part of the Group not the admin
