Adding code for NeoTrinkey Zoom shortcuts. NeoPixels act as visual UI to tell if your mic or camera are muted. Keyboard shortcuts for muting/unmuting are sent by touching either of the two cap touch pads. Holding down both cap touch pads exits the meeting and has the NeoPixels do the rainbow cycle animation
