Topic: Setting up plug-in in Pro Tools First on Mac

I'm new to Pro Tools First (Mac) and would like to use Pianoteq 6 as a plug-in, but it's not showing up. Some instrument inserts are found, such as Sibelius 7.5 and Xpand!2, and they work fine. In Library/Audio/Plug-Ins, there are Pianoteq 6 plug-ins in the folders VST, VST3, and Components, but there is no AAX folder (AAX is the file format for Pro Tools plug-ins).
