According to the manual, you can do PC connection using Bluetooth, so give that a try. I found a teardown video and at least the top side of the PCB connector doesn’t have too many connection points. Some high quality pictures of both sides could help identify the likely pinout, and a breakout board would confirm. I would give Bluetooth a shot first.
I would argue that shopping for a person is different than straight delivery. Depending on the shopping, I could be convinced that tipping could be appropriate.
