Reproducible on a headset I own

It works that way on YT music

• 2 clicks: play/pause (2 times)
• 3 clicks: play/pause (3 times)

App in background:

• 1 click: play/pause
• 2 clicks: next
• 3 clicks: next and play/pause

Steps to reproduce

1. Plug this kind of headset: https://www.amazon.fr/gp/product/B0CDZP2LSC/
2. Start a playback
3. Use the clickable button to perform play/pause, next or previous
