Hi @Tiago C
Thank you for posting your query on Microsoft Q&A.
I am Saiteja from Q&A will be assisting you with your query.
Based on your query, here is my understanding: I see you have configured policies with MSAL Angular and would like to use iframe to make the application more single page instead of redirections.
Here is the Microsoft document that would help you in implementing iframe to make the sign up the sign in simpler and more impactful. This document helps you in achieving the embedded signing using <iframe>HTML which embeds Azure B2C sign in user interface directly into your application.
I hope this information is helpful. Please feel free to reach out if you have any further questions.
