Hi @tdipisa
Kindly clarify these,

1. Do we have to support marker type symbol, if so we cannot display icon text that is essential to associate the marker with carousel item
   
2. Now that we are required to display icon text on the marker, we can hide the Icon field in the styler component ?

Not strictly needed for GeoCarousel, the Type field can be hidden in this case

2. Now that we are required to display icon text on the marker, we can hide the Icon field in the styler component ?

Yes
