I have created a greyscale google map through creating an API through Google cloud.
I have entered the longitude and latitude, but not sure how to add a marker.
At the moment, the map is zoomed out and not zoomed in enough to show detail of the address I want to marker.
The purpose of this map is to show our business address (and want to keep it grayscale)
I have added a marker, however it has whited-out the map itself and only shows the red marker and content title
