How to Collabolate with Cesium for Unity and Mapbox

I would like to collabolate with Cesium for unity and Mapbox
Specifically, I want to put Cesium’s 3DGlobe on a Mapbox map in Unity.

CesiumJS has something similar, but Cesium for Unity does not seem to have anything similar.

Therefore, I would like to create a new use case.
Is it technically possible to do this specifically?
If possible, what logic do you think could be used to complete the project?
I would appreciate it if someone could enlighten us.
Thank you in advance.
