Selfie style remote?

I see a lot of videos where new guys trying to take selfie videos on efoil but they straggling doing it because in one hand they have remote and another the action cam.
Why no one using 2in1 decision something like this

when action camera could be mounted on remote or even able charge from remote

when you have some sort of grip with action camera mount and you are able insert remote to that grip

when you have some fixation on the wrist and some long stick for 360 videos (not the best image example due safety, but I’m sure you understand which fixation on the hand could be used)
