Gremsy Pixy U with Herelink. Who has this working?

I’ve been using tilt via SBUS but would like to get this working with Mavlink.

This document states Channel 6 for tilt:…/common-gremsy-pixyu-gimbal.html

This one state Channel 10 for tilt:…/36000222529-control-gremsy…

Typically, this wouldn’t matter as these should be assignable.

That said, Gremsy has specific channels baked into their firmware with respect to gimbals and Herelink.

I can’t get it to work with either though.
