Placing your Snippet on a Wix site
So we can't, obviously, create a bar that spans the page as everything is restricted to a Wix frame - It is done on purpose by Wix.
This is a commercial decision by Wix. They only allow apps that are approved and in their store (basically they charge for them and take a cut).
You CAN place our bars on your Wix pages using using the 3rd Party Overlay.
