Midi note Control of Hide/Show set list

[KeytarPaul]

I'm using the More Buttons Layout for the Hide/Show toggle of the set list with 2 finger taps.
I set an App control for Midi Note Click to Show/Hide Document Viewer after Two-Finger Tap but it's not working.
Any help?

You can click the MIDI button in the top toolbar and look at the Activity Log to see if the MIDI message you're sending matches the MIDI message you mapped the action to.

Or you can submit a help ticket and we can look at your settings.
