Please note that you have to use an appropriate PlantUML code for this feature. Code that does not use the map features at all will (understandably) result in an empty map.

In the background of the attached image I can see that the used code does not use the map features, since the fifth button for the map in the upper right corner is not displayed. I suspect at this point that you have used the standard Bob -> Alice : hello example.

Tip: Use the code example from the documentation you linked. After that you should be able to see something.

Please note: here

1. the Map button is shown,
2. the link inside the image is clickable.
