Make it easier to find and enter the coordinates for a scene location on the globe

Many AEC users of Cesium Native plugins have workflows that start with finding the lat long for the location of their scene, and then pasting the coordinates into plugin fields in the editor. They usually get the coordinates in an external application like Google Earth or a CesiumJS sandcastle.

How can we make this easier and possible with our plugins?

No files, tests, or entry points are identified. First clarify which Cesium Native plugins and editor targets are in scope, then define the proposed coordinate-entry workflow and how users will know it is complete.
