I am a bit confused about how to trigger MFA using just an email that users input inside the bot. If I'm using Azure AD do I have to create an Azure Function that will trigger MFA as soon as the user starts a conversation with a bot or can I use action flow inside the bot and trigger MFA via HTTP request? The logic is that user will start a conversation with a bot, which will trigger MFA using Azure AD and send a verification code to the user's phone.
Configure manual authentication for your copilot and let Entra ID (AAD) do the rest. If your users fall under a policy that requires MFA - an MFA flow will be triggered
