Password masking for Rasa bot

Hi, We have created a Rasa chat bot and integrated in Microsoft Teams. We have a query regarding password masking - While an user is chatting with the bot, if the bot asked the user for password for authentication, it should be displayed in ‘******’ format. Please let us know how to mask the password while chatting - whether it is possible to do it in between the chatting with the user.

Thank you.

If Microsoft Teams allow you to change their interface - specifically the message bar, then you can do that by sending a Custom Output Payload with your response, then detect that payload in Teams and change the UI.
