Highend Theme Google Maps API show empty blue field

I’d like to ask for help displaying a map on my website in the Highend theme.

As others have posted I have acquired a Google maps API key and I entered the geo coordinates into the fields.

Unfortunately, the map is showing an empty blue field with a red pointer in it.

I hope I don’t need to be a coder or something to get this thing to work. Because I’m a photographer. I’m hopelessly lost and unable to find an answer, at least not in the language I understand.

Thanks for any help.
