Missing log-in button in Teams deployment with Azure AD v2


I created a Bot using PVA web and published it to a website and Teams.

The bot requires signing in and this is how it looks on the website:



But in the Teams conversation, there is no "sign-in" card as should be (nothing shows up after this message):



What can I do in order to allow users to authenticate via Teams (using the "log-in" button)?

Hi @Shira1 ,


It's normal in Teams channel, take a look at this documentation here:

Once the user enters their username and password in the prompt (hosted by the identity provider), they might be prompted to enter a validation code, depending on the channel. Some channels, such as Microsoft Teams, do not require the user to enter a validation code.

Thanks for your response! Though if the user is not required to enter the validation code, why am I transferred to the "sign-in" topic? And what can I do in order to continue with the conversation (since now I can't reach any other topic, the bot is not writing anything)?
