How to set the size of a circle in the map component?

I’m trying to display a circle on the map component in the universal GUI (2022.2.13 b2.0) But nothing I do seems to alter the size of the circle. I’ve tried giving it two coordinates hoping that this would set the size but the circle remains the same.

{

        "CoordSets": [

               [

                       {

                               "Lon": "10.865400",

                               "Lat": "55.565922"

                       },

                       {

                               "Lon": "10.865400",

                               "Lat": "56.0150816223465"

                       }

               ]

        ]

}

The docs don’t ever seem to mention the circle geometric type for the map component. How is this supposed to work?
