Support request: Companion module behringer-xair

Dear GitHub Community,

Succesfully I made use of the companion module behringer-xair to extend my Elgato Streamdeck functionality.
However I’m tyring to make use of some functionality without any success.

In short: I’d like to manage the fader setting for a dedicated channel.
However all my attempts result in a fader setting for the Main Out mix.
What I want is: to set a fader setting for a channel of one (or more) of the Auxilar Busses.

Therefore my question, What should I change or do in order to make the necessary setting (setting fader for Auxilary Bus in stead of (default?) Main Out.)

Background:
Main Out is used for on stage audio
Auxilary Bus (2 channels for stereo out) is used as separat audiomix for livestream.

Kind regards,
Ingmar

Dear GitHub Community,

At last I managed to find the solution myself.
Instead of Behringer XR: Fader Set (which only affects the fader for Main channels) I should have used Behringer XR: Send Level Set.
If you select this action the preferred Channel, BUS and Level can be set.

Solution found.

Kind regards,
Ingmar
