ARA Extensions

I am searching how to add ARA Extensions / Event Fx to audacity effects .
I want to use RipX as an effect in audacity.
It appears in effects list but says you have to add as ARA Extension / Event Fx
I am not able to find the process anywhere

Can somebody help me?

Audacity doesn’t support ARA, so even if you somehow can get it to run, it likely won’t work as intended.
