Render a Polygon by passing data with OSM map component

Hi people. I'm in need of a solution for this situation: I'm using the OSM map component and I need to render a polygon / region in the map by passing a list of coordinates.

Basically, a user can select from a list of regions. When the user selects region X, the map updates and shows the region X.

Sadly I can't find a way to render polygons with this plugins, I can only render markers individually.
