If you use Amazon, it looks like they have a 10-ft version of what you need for about $9 ($8 with Amazon Prime).
Search Amazon for “USB Type C Cable Fast Charging 10FT,UDATON”
It’s the first non-sponsored result for me and it’s marked “Amazon’s Choice”
ETA: Upon looking again, I’m not positive that’s a 3.1 and I see you specified that… hmm. I see a few at 3ft but not a lot is coming up at 6+ ft.
