Right now your terminal isn't on Google at all, and there are two separate reasons for that:
1. It isn't published yet. Google can only find pages that exist at a public web address. Hit Publish (top right) to deploy it — you'll get a real URL like london-top-gear.vercel.app, which you can then open on any phone in the shop.
2. Even once published, Google can't see past the PIN pad. Every page sits behind the sign-in screen, so a search crawler hits the lock and gets nothing to index. That's actually correct for a shop tool — you don't want your inventory costs and revenue showing up in search results. The techs should reach it by bookmarking the URL, not by Googling it.
So the practical answer: publish it, then save the link to the home screen on each phone or tablet in the bays.
If what you actually want is to be found by customers searching "tire shop London Ontario," that's a different thing — a public landing page with your address, hours, phone number, and services, sitting at the front of the app while the PIN-protected terminal stays tucked behind /terminal. That page can be indexed, and it's what would pair with a Google Business Profile.
