Plug-in and hosting Purchased - now what?

I’m new and just starting out with this app and Bias Fx 2 and have a lot to learn, but what is the benefit of the Plug-in and hosting add-on? I paid for it but not sure what it’s suppose to do. I don’t see any difference or added options or benefit during use.

The hosting/plugin IAP lets you play 3rd party synths on App Store and also lets you use MG inside 3rd party hosts, as a plugin. Technically, the IAP suppress the interruption dialog, that otherwise comes up when using as a free trial.
