Unable to validate Location Picker API Key

I’ve tried setting up the API key as this video shows (https://www.youtube.com/watch?v=IeEhojZf_L8&ab_channel=Reservety) but I always get the same message error:

Loading the Google Maps JavaScript API without a callback is not supported: https://developers.google.com/maps/documentation/javascript/url-params#required_parameters

Those are the parameters I used.

It would be so much appreciated any help.

Thanks.
