linking plugins so they both edit at same time

cubase 10.5 pro. looking for a way to link two plugins so that when I edit one of them, the other edits at same time. is this doable?
two separate tracks, each with the same plug as an insert.

Link or Qlink the channels.

I have tried this but not having much luck. Talk to me like I’m 5 years old, how do I do this? I have 2 guitar tracks L and R and I want to put a Waves C4 on each and control one but have the other respond to my changes.

GOT IT! DUH… i had to have both tracks ACTIVE for it to work… wow… I’m a bonehead.
