How to fast forward in YouTube app on iOS using bluetooth remote?

Question

I am using an ArcX (http://arcx.fit) bluetooth remote.

I want to be able to hold left/right arrow to fast-forward and rewind YouTube videos.

The commands sent when using the remote buttons can be rebound.

Does anyone know if the YouTube app listens to any keyboard shortcuts?

I am currently looking into assistive touch accessibility options:

• Mouse Keys

• Gaming Controller support

UPDATE

• Holding down a finger on the screen plays at 2x fast-forward.
• YouTube in Safari can listen to left and right arrows.
• iPadOS apparently responds to cmd+left/right and other shortcuts.
• There is a Premium feature called "Listening Controls" which puts the +/- 10s button on the screen for single touch - maybe this is addressable via SwitchControl or something.
