Magic Trackpad media controls

Hello all :waving_hand:t2:

I hope you’re doing well.

I’m trying to use my magic trackpad 2 as a media remote of sorts (I don’t want to buy the siri remote), but I haven’t figure how how to do a (1 finger or multiple fingers) drag from bottom left to top right to increase the volume and vice versa. Does anyone have this configured? I suspect it’s an custom and advanced configuration, but so far it’s giving me right old a headache!

At the moment I have 1 finger click bottom right as volume down, and and the same gesture on the top right as volume up.

Thanks in advance.
