Expected/desired behavior

I want to add authentication to the solution using Entra ID. I don't want to use the authentication configuration in the azure resource. I want to have control of the authentication process in the code of the app.
What would be the best way to implement it? Should I add the authentication code in the ClientApp project with MSAL? Should I add the authentication code in the SharedWebComponents project? In MinimalApi maybe?

Mention any other details that might be useful

Thank you very much for your help
