No instructions, can’t figure out how to use – Find My Parked Car Review

The description says all you need to do is “tap the button” when you park your car. But what button????????? I see a few icons and have tried tapping all of them but there’s no indicator of or how it worked. Also no instructions that would tell you how to use the app later to actual gigs your car. It’s not intuitive at all and since it doesn’t come with instructions, it is worthless to me.
