Google wants one unbroken video that shows where you are, that the business is real and that you run it. Start outside with a street sign or the shops next door, then your sign if you have one, your van or your tools, then something only the owner can show, like unlocking the door. Google tells you why it turned a video down. Fix that before you try again, as you only get a few goes.
There’s more on this in my Google Business Profile Verification Guide.
