     Creates a new prompt that asks the user to sign in using the Bot Framework Single Sign On (SSO) service.
-    The prompt will attempt to retrieve the users current token and if the user isn't signed in, it
-    will send them an `OAuthCard` containing a button they can press to sign in. Depending on the channel,
-    the user will be sent through one of two possible sign-in flows:
-    - The automatic sign-in flow where once the user signs in, the SSO service will forward
-    the bot the users access token using either an `event` or `invoke` activity.
-    - The "magic code" flow where once the user signs in, they will be prompted by the SSO service
-    to send the bot a six digit code confirming their identity. This code will be sent as a
-    standard `message` activity.
-    Both flows are automatically supported by the `OAuthPrompt` and they only thing you need to be careful of
-    is that you don't block the `event` and `invoke` activities that the prompt might be waiting on.
-    Note:
-    You should avaoid persisting the access token with your bots other state. The Bot Frameworks SSO service
-    will securely store the token on your behalf. If you store it in your bots state,
-    it could expire or be revoked in between turns.
-    When calling the prompt from within a waterfall step, you should use the token within the step
-    following the prompt and then let the token go out of scope at the end of your function
-    Prompt Usage
-    When used with your bots `DialogSet`, you can simply add a new instance of the prompt as a named dialog using
-     `DialogSet.add()`.
-    You can then start the prompt from a waterfall step using either
-     `DialogContext.begin()` or `DialogContext.prompt()`.
-    The user will be prompted to sign in as needed and their access token will be passed as an argument to the callers
-     next waterfall step.
