Need help Testing Azure Spatial Anchors in Unreal Engine 4.26 using hololens 2

Question

So I just finished implementing the spatial anchoring to my MRPawn for my unreal engine project and now I want to test it but I don't know how to acutally test it. I already checked the documentation for azure spatial anchoring and there's nothing on how or where to test to see if it works. Is there a procedure or tutorial on how to test it or how to implement a button of some sort.

Take a look at our sample OpenXR project here:
https://github.com/microsoft/Microsoft-OpenXR-Unreal/tree/main/MsftOpenXRGame

A right-select will spawn an ARPin at your hand's location and add it to a list of anchors to be converted to ASA anchors:

Then a voice command will upload those anchors to the cloud:

Finally, cloud anchors are located from an ASA watcher:
Create the watcher:

Subscribe to the ASAAnchor Located Delegate:

(AzureSpatialAnchorsEvent is a component that needs to be added to the blueprint)

And finally load a local pin from anchors the ASA watcher finds:

Note that this function will change the ARPin model to a green material when an upload has succeeded - do not close the project until the anchors have uploaded.

Note also that Azure Spatial Anchors will not work over remoting, you will need to run your project on a HoloLens
