How to import fxp files into Halion SE

Hello everyone,

I am new here and I am new to Cubase, so please bear with me. I’ve dabbled in Cubase for all of one week.
I would like to load a drum kit that is in fxp format. Those fxp files are on an external hard drive.
I cannot seem to figure out how to load/import/install them into my Cubase library. I have been playing around with the stock sounds that I downloaded from Cubase but I cannot bring in these fxp files.

For reference, I have Cubase LE AI Elements 11 on Windows 10. I understand that my version of Cubase is considered a lightweight version for now. I plan on upgrading to the more robust version at a later date. Does it have anything to do with versioning?

Thanks so much for your help!
