I want to trigger an audio with a custom hand gesture

Hey there beautiful community, I’m trying to create a custom hand gesture, actually with both. It’s like a japanese kanji.

When the user does that I’d love to trigger an audio, I figured out how to do the audio part but the custom gesture is hard.

Did anyone find it out?
How can I do it?

I’m tracking hand values and maybe looking at them and creating custom matchs but Idk if its the way.
