How to transfer data from a waterfalldialog to another?

I am working on a bot framework project (C# - Bot Framework v4) which contains at least 2 dialogs. I want to transfer informations that I've created (not from the user) from a first dialog to another one. How can I do it ?

I tried to set the second parameter of the BeginDialogAsync function but it was empty on the arrival.

EDIT :

I have a first dialog (SignInDialog) which is used to connect the user with OAuthPrompt. When the user is connected, in the same class, I will then handle his intent with the Dispatcher (Microsoft) and LuisRecognizer, to tell if I have to use QnA or LUIS.

What I am trying to do is to call a specific dialog located in another Dialog class (PersonalInfoDialog), according to the user's intent. But whenever I pass some arguments to the BeginDialogAsync method, I don't find a way to get it from the destination dialog.

SignInDialog class

        private async Task<DialogTurnResult> PromptStepAsync(WaterfallStepContext stepContext, CancellationToken cancellationToken)
        {
            return await stepContext.BeginDialogAsync(nameof(OAuthPrompt), null, cancellationToken);
        }

        private async Task<DialogTurnResult> DispatchStepAsync(WaterfallStepContext stepContext, CancellationToken cancellationToken)
        {

            var tokenResponse = (TokenResponse)stepContext.Result;
            if (tokenResponse != null)
            {

                var recognizerResult = await BotServices.Dispatch.RecognizeAsync(stepContext.Context, cancellationToken);

                var topIntent = recognizerResult.GetTopScoringIntent();

                var intent = topIntent.intent;

                switch (intent)
                {

                    case "CASE_1":
                        return await stepContext.BeginDialogAsync(nameof(PersonalInfoDialog), recognizerResult, cancellationToken);

                    case "CASE_2":
                        ...
                    default:
                        Logger.LogInformation($"Dispatch unrecognized intent: {intent}.");
                        break;
                }


            }

            return await stepContext.EndDialogAsync(null, cancellationToken);
        }

PersonalInfoDialog class

Here, in debug mode, test is null. 

    private async Task<DialogTurnResult> PromptStepAsync(WaterfallStepContext stepContext, CancellationToken cancellationToken)
    {
        var test = stepContext.Options as LuisResult;
        return await stepContext.BeginDialogAsync(nameof(OAuthPrompt), null, cancellationToken);
    }

Thanks for the help.

If I understood you correctly and you really have no other options to transfer the data in one Waterfall-Dialog:

You could use state property accessors to store/ load the data. In the Docs you find a example. Have a look at the UserProfile: https://learn.microsoft.com/en-us/azure/bot-service/bot-builder-howto-v4-state?view=azure-bot-service-4.0&tabs=csharp

And for more information I recommend the Doc article about states: https://learn.microsoft.com/en-us/azure/bot-service/bot-builder-concept-state?view=azure-bot-service-4.0
