Map Bubble Confusion

Being new to GeoDirectories (testing the free version, about ready to buy) I must say that it is kind of complicated to get the details behind the Map Bubble:

1. I read that changing map-popup.php is the way to go. (https://wpgeodirectory.com/documentation/article/how-tos/customizing-templates/)
2. Then I found some ccs on GeoDirectories website to modify the Map Bubble. (https://wpgeodirectory.com/docs-v2/faq/common-examples/)
3. Finally I encountered the option to change the GeoDirectory Settings in the WordPress backend (Add listing form) which has effects on the Map Bubble.

I wished that this would be way more intuitive!

I have two questions:

1. Is there no clear path to modify the Map Bubble?
2. After buying the Pro version will I get support on how to make changes to the Map Bubble using CSS?
