RTSP simple server installation

I am a noob so please be gentle. I am struggling getting my eufy non RSTP supported cameras up and running. I have eufy security installed. The documentation says I need RTSP simple server add-on and i can not figure out how to install it. It is not showing up in the add-on store. How do I do this?

I don’t know anything about this particular AddOn, but many are made by the community and are not included in the store. However you can manually include it… On the AddOn page, there are 3dots at the top right, so click on it, select repository, and add the GitHub URL for this particular AddOn.
