Replacement wrist strap for Quest 3S controller

Hello! I have a Meta Quest 3S that is still under warranty. I lost one of the original wrist/safety straps that came attached to one of the Touch Plus controllers.

I only need a replacement wrist strap, not a replacement controller. I checked the support options, but there doesn't seem to be an option specifically for the controller wrist strap.

Could you please help me get a replacement strap?
