As this is such a new system your choices are limited to Apple. As it turns out Apple now offers parts directly! Here’s the main site Apple Self Service Repair
So… jumping to the also available MacBook Air (13-inch, M3, 2024) Repair Manual we can see if Apple offers the needed part, sadly they only sell it with the trackpad Exploded view and available parts select the color of your system and follow the first link on ordering it.
Your other option is a bit iffy right now as getting recovered parts from damaged systems would be something I would pursue in older systems as an example TheBookYard in the UK has the part listed just not available, even still I would email them to see if they have it if you live in the EU.
