Actually, what I was looking for was an arrow with a location showing latitude and longitude, and I didn't have one. Here's what I did to avoid having an arrow:

1: Left-click on a point on the map. A grey dot appears

2: Right-click on this grey dot and share this location

3: Click on the ‘Embed a map’ tab

4: Copy and paste the iframe. Then, if there are no businesses at this point, a map without a dot will be displayed

Result:
