How to get 4 funger touch to open new tab (Command T)

This new version doesn't allow me to manually assign "Command T" to 4 finger touch on trackpad
It only has preassigned commands.
Thanks, Bob

Are you tapping or clicking or a force-touch gesture like pressing hard?

You mean like this?

What doesn't work for you there?

Yes I got it working about 20 minutes after I made the first post here.
Thanks for all your help it's a great tool
