Default github Unity build action dosen't work with Cesium

Cesium for Unity
1

I’ve tried using the default build action for Unity via the GitHub workflow, but it didn’t work due to Cesium dependencies.
Is there a “default” workflow for Unity build that uses Cesium that I can use?
Can I use cesium as an imported UPM package, rather than a submodule?

Note:
Also added it as a bug in the GameCI repo Unity builder fails when building a game with CesiumforUnity package · Issue #720 · game-ci/unity-builder · GitHub

Error:
-Missing Implementation for Partial Methods
error CS8795: Partial method '...' must have an implementation part because it has accessibility modifiers.
-Missing ReinteropNativeImplementationAttribute / ReinteropNativeImplementation
error CS0246: The type or namespace name 'ReinteropNativeImplementationAttribute' could not be found (are you missing a using directive or an assembly reference?)

Adding Cesium for Unity via UPM is pretty simple. Check the first step of our Unity Quickstart guide: Cesium for Unity Quickstart – Cesium

If you’d like to build Cesium for Unity via CI instead, you might want to take a look at this comment I left on a similar question: CI/CD Fails After Adding Cesium for Unity – Partial Method and Reinterop Errors - #2 by azrogers
