Herelink button setup via QGC

So I use a seagull camera trigger for sony a6000 with herelink. Whenever I try to setup a button for camera trigger it does not work. I followed the steps correctly and the camera does take photos if I trigger it via mission planner from laptop. But I cannot trigger by setting a button in herelink

I assume you are setting mavlink buttons?
Does it work in Solex?

I haven’t tried solex yet.
