How to deal with (Unity as Library) embed in (Native MacOs App)?

Can Unity be integrated into MacOs native App as a library?

• GitRepo: https://github.com/Unity-Technologies/uaal-example
  
  In this official project, Unity shows how to embed Unity into Android, Ios, tvOs. But it does not show how to embed Unity into MacOs.
  
  

• ManualUrl: https://docs.unity3d.com/Manual/UnityasaLibrary.html
  
  

In this official document Url, it is officially stated that Unity can be integrated into three platforms in the form of Library: Android, IOS, Windows and the Universal Windows Platform

• Unity2020.2.0f1c1 can also export the Mac package as an Xcode project.
  
  

I understand that Unity can also be made into a form similar to the above GitRepo on the Mac side, integrating Unity as a Library into the MacOs native App.

• So I Would like to ask the official staff or other development partner：

Is there a similar demo on the Mac side?

Is there a method, demo, or idea that allows Unity to connect to the MacOS native App in the form of a library?

Any ideas or clues are fine. If there is an answer, thank you very much~
