Saving Mesh on iOS/iPadOS

I am pretty new to ARKit/RealityKit and am trying to build an app that would, on an iPad or iPhone that has access to a LiDAR sensor, save the mesh data of the field of view of the seen environment and save it to a document 3D document that would later be used to make measurements as a post-processing action.

For now I am unsure on how to start on saving the mesh that is visible in debugging. I am thinking about saving the ARMeshAnchors and their corresponding geometries and maybe convert the whole list into a USDZ (or similar file). Would this be the right approach or am I going completely the wrong way?

Would appreciate any help!

Thanks in advance
