Mac plugin debug

I tried to develop a RhinoCommon plug-in for Mac and followed the example, but there was a problem that hindered me:

After clicking the run button, does Rhino automatically start and load the plug-in? (Because mine does not automatically start, nor does it automatically load the plug-in, if not, what do I need to do?)

VS 2019 for Mac
R6
It is worth mentioning that: the build plug-in, manually installed can run in Rhino

I don’t know what I missed?
Anyone can help, thank you very much!
