Bumping this because I have exactly the same issue. I did find a 4-port USB hub via Wirecutter (https://www.nytimes.com/wirecutter/reviews/best-usb-c-hubs-and-docks/, which lists, but did not recommend, this: https://www.amazon.com/dp/B09BNXMHSL. Not horrible, but I'd prefer 10 GB if possible. Any suggestions?
Take a look at these (in no particular order and I'm not endorsing any of them):

all of which came from a search of "usb-c to usb-c hub":

HTH.
Thanks much u/AllMyFrendsArePixels! Alas, that's entirely the wrong answer ;) You were supposed to say, "Oh, sure, just go here <enter URL>." Rats! I guess I'll just go with this, even though the power is a bit iffy and the speed is a bit low: https://www.amazon.com/dp/B09BNXMHSL. Right now I just need to hook up two backup drives...
