How do you reset Bluetooth on Macwheel MX PRO without the passcode?

Hoping someone knows how to do this. My wife had to factory reset her phone and while we have no problem connecting to the scooter with Bluetooth via the MACWHEEL app, she can't remember the Bluetooth password.

Does anyone know of any way to reset the scooter so that it resets the Bluetooth password? I can't find anything about this online and it's not in the manual. We've tried 000000, 123456 and 654321 and none of them work. We're stumped!

Thank you in advance!
