Google Map doesn't load (MissingKeyMapError)

[keyston7]

Problem:
I added a map to my website but it does not load.

What I did so far:
I opened the Java script and saw this error message:
maps.googleapis.com/maps/api/js?v=3.exp&sensor=false&libraries=places:35 Google Maps API error: MissingKeyMapError https://developers.google.com/maps/documentation/javascript/error-messages#missing-key-map-error

I got API Key from Google (Instruction at: https://churchthemes.com/page-didnt-load-google-maps-correctly/)

I tried to look under properties of the map item in web builder, but I could not find a place to input the Google API Key.

Question:
How can I input the Google API Key into web builder?

Thank you

I know that everybody is having the same problem - Google maps does not load.
Anybody knows how to input the Google API Key into web builder?
