[FEATURE] Use Icons to symbolize geospatial field in document layer

[VijayanB]

Is your feature request related to a problem?

In document layer, maps can only show markers as circles, it will improve user experience if users were able to choose an icon over marker as circle. This feature request is to use one icon for all values from same field.

The icons can be either custom icons ( uploaded by users ) or dashboard maps should provide popular icons to choose from.
