What are the steps to enable an OTP Phone Authentication for Power Apps Portal? My initial research (https://docs.microsoft.com/en-us/powerapps/maker/portals/configure/configure-portal-authentication) make me believe that I can setup Azure B2C for Authentication and in here (https://docs.microsoft.com/en-us/azure/active-directory-b2c/phone-authentication-user-flows) shows that I can setup an OTP only phone sign-in experience.
In context of Power Apps Portal that connected to a Dynamics 365. I wanted to do the followings:
Is it by any chance possible to do (is my planned Flow logical?) and if it is, what are the steps that I need to take to achieve it?
