Autotune plugin installed and seemingly working, but not visible to use properly

Hi, I hope someone can help.

I am running audacity on Mac OS Mojave and have just installed two Autotune plugins, Graillon 2 and Gsnap.

They seem to be working, but not visible when I select the plugin, Screenshot below:

If I select things from the settings it works, but there is nothing visible on to be able to use it properly.

This may be a silly question, but I’m not very clued up so any help would be much appreciated.

Thanks in advance!

Antares Autotune does not support Audacity.
A list of supported “host” applications is available on the Antares website: https://www.antarestech.com/host-daw-compatibility/
