Is there any documentation on how to turn on mixed reality capture for the Hololens2 on MRTK3?

[DanchGit]

I want to take a picture on my HL2 Unity app that has both the real world and the virtual objects.
I am unable to find any documentation on how to do this using MRTK3. This is the documentation I currently found:

https://learn.microsoft.com/en-us/windows/mixed-reality/develop/unity/mixed-reality-capture-unity

However, this seems to be for an earlier version of MRTK. To enable "Windows MR Camera settings provider", I need to "Select the MixedRealityToolkit object in the scene hierarchy." according to the documentation, however, there is no such object when using MRTK3. I only have the MRTKInputSimulator and the MRTK XR Rig.

Am I missing something?

I feel like this is something that definitely has documentation but I am unable to find the steps to enable mixed reality capture on MRTK3 for the Hololens2. Any help is greatly appreciated.
