For this instance, I used the Microsoft.AspNetCore.Mvc.ApiExplorer to inject IApiDescriptionGroupCollectionProvider, and tryaddenumerable for IApiDescriptionProvider, DefaultApiDescriptionProvider

I then created a help controller which provided me a list of string from looping into ApiDescriptionGroups.Items[0] then getting each relativepath. Also checking if there are ParameterDescriptions then getting all its name to stringbuilder to provide me the API description. Not bad but hehe. That's what the old man wants me todo. hahahah
