Laura,
I moved your post from Studio 2 to Surface Laptop Studio as you mention you have a Surface LAPTOP Studio.
The Surface Laptop Studio has two (2) USB-C ports on the left side of the device in the keyboard section.
If your needs are simple and you don't need all the ports on a USB-C hub, you can get an adapter for USB-A to USB-C like this one (which I the one I use) https://www.amazon.com/gp/product/B07XYTHCXV
