Reuse Microsoft Surface Pro 8 keyboard?

I found this keyboard in an e-waste bin. I believe it's from a Microsoft Surface Pro 8 or 9. Visually it's identical to this: https://www.microsoft.com/en-us/d/surfac.... The model number is 1864. But I don't have the laptop that came with it.

The connector has 6 contacts. I suspect it's a USB HID interface, although the touchpad could be I2C. Before cutting it open (which is destructive), I wonder if anyone has some info on the pinout of this keyboard? Thanks.
