APEX

I am using oracle map in apex 23.1.

1. User draw a circle on the map and I am converting it to lat, lng and radius using SDO_GEOM.SDO_CENTROID and SDO_GEOM.SDO_DIAMETER which is working fine and then I store it into a collection.
2. when the user navigate to the map again I wanted to draw the circle again using lat, lng and radius from the collection, I try to look for any examples to get an idea about the javascript but could not find.

is any body aware how to achive this.

Thanks
