I have found this page on docfx site https://dotnet.github.io/docfx/tutorial/universalreference/gen_doc_for_ts.html and it mentions Type2docfx npm library. But what I found is that the latest version of Type2docfx doesn't work with the latest TSDoc & Typescript.
Also as per their GitHub repo Type2docfx is not in active development, so is there any alternative to generate docfx based documentation from Typescript.
If I use previous versions of TSDoc then Type2docfx works, but I lose many key features of TSDoc like only generating documentation of exported modules in the index.ts file.
