Long pressing on an widget not triggered

Describe the bug
Hey! I tried to assign a long press action to my app switcher widget (to show the dock), but this is apparently not possible. It simply cannot trigger a long press action. I then tried to trigger a long press action with the emoji widget, but this was neither possible.

Affected input device (e.g. MacBook Trackpad, Magic Mouse/Trackpad, Touch Bar, etc.):
Touch Bar

Device information:

  • Type of Mac: MacBook Pro (15-inch, 2018)
    macOS version: OSX 10.15.1
  • BetterTouchTool version: (3.207)
