Teamviewer (only): Gesture for hiding app (cmd-h) not working

I have configured 3 finger swipe down as cmd-h in order to hide any running app. This works fine with 2 different Magic Mouses on two different Macs except with Teamviewer (http://teamviewer.com/).

Affected input device (e.g. MacBook Trackpad, Magic Mouse/Trackpad, Touch Bar, etc.):
2x Magic Mouse

Device information:

  • Type of Mac: No 1: MacBook Pro 13" 2013, No 2: iMac i7 2013
  • macOS version: 10.12 (but also with earlier OS it didn't work)
  • BetterTouchTool version: 2.645 (but also with earlier versions it didn't work)
  • Teamviewer Version: 13.2.26559 (but also with earlier versions it didn't work)

Thanks for help!
