How to Unlock Segway G2 with Apple Watch?

Im tired of having to take my phone out of my pocket every time I unlock my scooter. I own an apple watch Ultra and Ive read online that it can be set up to just hover the watch over the screen and it will unlock. It mentions that I need to set up a key on the wallet app but I cannot find anything on the app to do so. I was wondering if anyone here has that setup and could point where it happens.
