What type of App should i choose to get installed within the Zoom Client?

I am planning to build a new fun app which the host and participants can play within the Zoom Client.
Out of the 5 types, (JWT, ChatBot, OAuth, SDK, WebHook Only) which type of app should I choose to start building. The app doesn’t need to interact with the zoom functionalities and can be considered similar to Kahoot or Slack.
