Load Halion Sonic SE 3rd party instruments

My issue is the same as the one described here: https://www.steinberg.net/forums/viewtopic.php?t=92797

I have Cubase Pro 8, which includes Halion Sonic, and I have a 3rd party instrument that I’d like/need to use.

On the link I’ve shared they mention that you need the full version of Halion Sonic to do this, however, I don’t know if the Halion Sonic version included with Cubase Pro is the full version.

If loading that instrument to Halion Sonic is not possible, is there another way I could use this instrument??

BTW, is HALion Sonic SE the version that I have.
