Scooter Registration-Is It a Thing? (workplace)

I am soon receiving a new (to me) scooter. While using it from the car and back would be most helpful, I can't load or unload it. However, I think I'm going to let it "live" in my office and just use at work. I work in a pretty large building and the food place and bathroom are really far for me to walk. Most days I just...don't (not great for bladder health). So with the scooter I'll be able to (yay!) As well as just go for a stroll outside on my lunchbreak, etc. Anyhow, I was talking with my work partner and they asked/ warned if I needed to register it. I'm like, huh? Why would I need to do that, it's a mobility aid? I held one of my crutches up and said I don't have to register these, do ppl register their wheelchairs? They're just looking out for me, to CYA, but honestly do I even need to bother with it? I just don't see the need, personally. Not because it's some secret, just because...it's for my health condition and kinda no one's business if I use a mobility device or which one or why.
