Update: was able to figure it out after playing with a different blueprint’s code to tailor it to the Paddle Pico
Didn’t know how to properly edit my original post to add the new blueprint without having to discard the old code, so I made a new topic for the new/modified blueprint: here
Thank you to GregTR and his work on Lutron Caséta Pico 4/5 Button Remote Advanced Actions (Core Integration)
