Hold mouse button + move gesture?

Hey everyone,

I've been trying to set up a custom mouse gesture in BTT and was wondering if something like this is possible

Basically, I'd like to hold down the side button on my mouse and then move the mouse to the left, and have that trigger an action (like closing the current app, for example).

Has anyone tried doing something like this? I feel like I'm missing something obvious :sweat_smile:

Any help would be really appreciated!
