Thanks for your question.
I saw that I didn't make some simple example of working with vector tiles, and I will try to add such an example in the next version of the asset.

The best way depends on two things:
1. How many models you want to place.
2. Whether you know the coordinates of the polygon points of the areas.

If there are not too many models (up to 100-200), it is better to use 3D markers.
Examples of how to create a 3D marker can be found in the atlas of examples.

If you have a lot of models, it is better to make a pool of objects and position them on the map using OnlineMapsControlBaseDynamicMesh.GetWorldPosition.

If you know the coordinates of the polygon points of the areas, good.
If you don't know them, you can find them using OSM Overpass API or get them from vector tiles.

When you have the point coordinates of the area polygons, you need to find a point within the polygon to place a marker or GameObject.
I would do it this way:
1. Find the bounding box for the polygon.
2. Got a random position inside the bounding box.
3. Using OnlineMapsUtils.IsPointInPolygon checked that the point is inside the polygon.

4. If it is inside the polygon, create an object.
5. Repeat from step 2 the required number of times.
