Retrieving Refresh Token with OAuthPrompt in Microsoft Teams Bot

Question

I am currently developing a Microsoft Teams bot and using the OAuthPrompt in my DialogSet to obtain the access token. The token retrieval works as expected, but I am facing an issue where the refresh token is not being retrieved along with the access token.

Is there any way to retrieve the refresh token using the OAuthPrompt? Are there specific settings or configurations that need to be enabled to obtain the refresh token in addition to the access token?

 AddDialog(new OAuthPrompt(
                   nameof(OAuthPrompt),
                   new OAuthPromptSettings {
                       ConnectionName = "xyz",
                       Text = "Let’s get started!",
                       Title = "Connect to your Account",
                       Timeout = 300000, // User has 5 minutes to login (1000 * 60 * 5)
                   }));

await stepContext.BeginDialogAsync(nameof(OAuthPrompt), cancellationToken: cancellationToken);

var

Hello Palak Agarwal ,

Thanks for reaching out in the Microsoft Q&A!

Retrieving refresh tokens directly with Microsoft Teams bot's OAuthPrompt isn't possible. For long-lived access, explore creating a separate web app using Azure Active Directory v2 (AADv2). This app handles sign-in and retrieves both access and refresh tokens, sending them back to your bot for secure storage and use in refreshing access tokens when they expire.
