How do I properly set up Palm Mute and Aftertouch?

I am using MG in Ableton, and noticed no different in playing when I activated the aftertouch and the palm mute dynamic features respectively.

Thinking it might just be that my synth VST isn’t registering these signals, I sent it through Bome which does a good job of capturing all MIDI signals, and I noticed that it isn’t the synth but MG doesn’t seem to be sending out any aftertouch at all, and only CC7 on value of 0, regardless of how palm muted or open I play the strings.

Have I set something up wrong?
