Cesium based 3d map

Hi, has someone tried to use some 3d map program, like Cesium, to make the mission and model visible in the 3d environment?
I have tried it on a simple program with mavlink direct connection and it works fine, but I haven’t the knowledge to implement this on mission planner.
I saw that in MP there is a 3D map but only in FPV.

There is a cesium plugin in mavproxy already
