Audio Plugin Host Editor not displaying created plugins

Hi there,
I have just built the Audio Plugin Host Editor from the develop branch and I can’t see any of the plugins I have created. They are in the folders where my DAW (Ableton Live) can see them.
I am on a mac OS (Catalina).
Any idea?

Cheers

You might suffer from this:

TL;DR: restart your mac, when you created the plugin the first time.

There might be a way to delete some cache file, but I don’t know which OTOMH
