How to install Open Gapps on RB5 AOSP image?

Hi, I was successfully able to install the AOSP 13 onto a RB5. It’s not really usable without Google apps. Where can I find the latest Gapps for v13? Seems like open gapps is not active anymore. There seems to be other groups providing gapps now. How would I install the zip package if I found one?
