How do I modify the GrabPointer prefab to allow for more than the default 64 colliders in a scene?

Question

I have a similar question to this, however for SpherePointer.

Using MRTK 2.2 as acquired by NuGet for Unity, I'm getting this warning pretty much every frame:

Maximum number of 64 colliders found in SpherePointer overlap query. Consider increasing the query buffer size in the pointer profile.
UnityEngine.Debug:LogWarning(Object)
Microsoft.MixedReality.Toolkit.Input.SpherePointerQueryInfo:TryUpdateQueryBufferForLayerMask(LayerMask, Vector3, QueryTriggerInteraction)
Microsoft.MixedReality.Toolkit.Input.SpherePointer:OnPreSceneQuery()
Microsoft.MixedReality.Toolkit.Input.FocusProvider:UpdatePointer(PointerData)
Microsoft.MixedReality.Toolkit.Input.FocusProvider:UpdatePointers()
Microsoft.MixedReality.Toolkit.Input.FocusProvider:Update()
Microsoft.MixedReality.Toolkit.<>c:<UpdateAllServices>b__63_0(IMixedRealityService)
Microsoft.MixedReality.Toolkit.MixedRealityToolkit:ExecuteOnAllServices(IEnumerable`1, Action`1)
Microsoft.MixedReality.Toolkit.MixedRealityToolkit:ExecuteOnAllServicesInOrder(Action`1)
Microsoft.MixedReality.Toolkit.MixedRealityToolkit:UpdateAllServices()
Microsoft.MixedReality.Toolkit.MixedRealityToolkit:Update()

I was able to successfully remove the similar warning for PokePointer using @Julia's response but I'm stumped as to how to do it for the GrabPointer prefab.

This prefab has a SpherePointer script attached but the SceneQueryBufferSize property isn't exposed in the inspector because SpherePointer's custom inspector (ShperePointerInspector.cs) doesn't expose it.

Great question! It looks like you've actually found a bug. Please use the following code to work around this for now, we will post a fix shortly. The issue to track this is here: issue 6878

            spherePointerFoldout = EditorGUILayout.Foldout(spherePointerFoldout, "Sphere Pointer Settings", true);

            if (spherePointerFoldout)
            {
                using (new EditorGUI.IndentLevelScope())
                {
                    EditorGUILayout.PropertyField(sphereCastRadius);
                    EditorGUILayout.PropertyField(sceneQueryBufferSize);
                    EditorGUILayout.PropertyField(nearObjectMargin);
                    EditorGUILayout.PropertyField(triggerInteraction);
                    EditorGUILayout.PropertyField(grabLayerMasks, true);
                }
            }

            serializedObject.ApplyModifiedProperties();
        }
    }
