Interaction with VR using Unity 2021.3

The Unity Learn page for adding interaction to a VR scene is either outdated or doesn’t give you credible information. For example, it tells you to add “XR Grab Interactable” and “XR Ray Indicator” components, but they don’t even exist. Does anyone know how to make interaction possible with the 2021.3 version or older?

1.3 - Grabbable Objects - Unity Learn

Have you installed the XR Interaction Toolkit from the Package Manager?

Those components are part of that package.

I am using the “VR Project Template” with the 2021.3 version which apparently doesn’t come with the XR Interaction Toolkit, and it is not listed under the Unity Registry in the Package Manager. The XR Interaction Toolkit is available when I use an older version such as 2020.3. Do you think I should just use that version instead?
