Collection of third party apps?

Is there a repository for Tizen OS (2019 TV) installable apps that you can try out, like the emby beta version app that can be installed through “userwidget”?
In a sense an “app store” for hobbyists?

Thought I’d ask before spending more time searching.

Having trouble with an a video app showing all material as 4:3 so… when finding this forum I thought it might be fun to hang around.
