Custom Map Marker

Hi,

I use JEM 2.2.2 on Joomla 3.8.3.

The JEM map shows a blue map marker, while Google's standard is some red marker.
I can't find in the settings how you managed to change from red to blue – or even better: how to use own designed markers.

Thanks for guidance!

in media/com_jem/js there is googlemap.js in line 42 there is the icon with the colour

Thanks!

A simple exchange of image path was too simply thought of me. Thanks Google, you want it more complicated and show nothing!

But anyway I know the place where to start further investigation, now.
