For some reason, the github page here https://github.com/microsoft/BotBuilder-Samples has no instructions on how to actually add the sample/functionality to your own bot.
I'm trying to add this library to my composer bot project: https://github.com/microsoft/BotBuilder-Samples/tree/main/experimental/handoff-library but it itself doesn't have any instructions either, just how to download it via git (which I've done).
The only guide I could find is here: https://docs.microsoft.com/en-us/composer/how-to-add-custom-action?tabs=csharp but it doesn't quite match up with the library above.
Am I missing something obvious?
