Having trouble getting NLP to work on Lightroom 6

I’m using a 2020 Macbook Pro (without an M chip) updated to Ventura 13.4 and using Lightroom 6. Ran the installer perfectly fine, but the shortcut doesn’t bring up NLP. I added the shortcut to my keyboard in system settings, but still nothing. In my profiles drop-down in Lightroom, I see Negative Lab, Negative Lab v2.0, and Negative Lab v2.3, but these do nothing. I’m running the free trial to compare to lab scans because I’ve seen great things about this plug-in and really want to purchase it, but not if I can’t get it to work.
