I am working on a project with asp.net web api in back and angular in front. I have set up normal login in my application. I need to add login with azure as well. How can I do azure login with MSAL along with normal login without using MSAL.js just using web Msal. I also have some example of azure signin with msal using MVC controller. Then how can I connect MVC and api sending access token to frontend application?
