Touchscreen not working on Dell Inspiron 14 2-in-1 Chromebook 7486

Hi, I've been trying to get the touchscreen to work on a Dell Inspiron 14 2-in-1 Chromebook (7486). I tried the xf86-input-cmt drivers, but no event responds to the touch screen so I assume there must be a problem with the device not being recognized by the kernel or something. It's a fresh Arch install, running Linux 5.7.10-arch1-1. I'm not too familiar with troubleshooting Linux issues so at this point I think I need some help since I don't even know what I'm looking for. I tried GalliumOS 3.1 as well, and it doesn't work on that distro either.

Here's the output of dmsg:

And here's lsusb:
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub

Bus 001 Device 002: ID 8087:0a2a Intel Corp.

here's xinput --list:
