12. Configure project settings for OpenXR
1. In the Unity menu, select Edit > Project Settings… to open Project Settings.
2. In Project Settings, select Player > Publishing Settings, then in the Package name field, enter an appropriate name
"Package name" is a unique identifier for the application. You should change this identifier before deploying your application to avoid overwriting previously installed applications.
"Product Name" is the name displayed in the HoloLens start menu. To make applications easier to locate during development, put an underscore before the name to sort it to the top of any list.
13. Update project settings
In the Unity menu, select Mixed Reality->Project->Apply recommended project settings for HoloLens2 to update the current development environment.

6. Save the scene in the project under Asset > Scenes
15. Import the sample scene
1. If you imported the Mixed Reality Toolkit Examples package in Section 3.3, click Mixed Reality->Toolkit->Utilities->Import directly Examples from Package (UPM), open the Package Manager window
2. In the list on the right side of the panel, click the "Import" button next to the sample scene name to import
