Auth pages with auto render mode in blazor

[MahdiElahi]

I want to build a Blazor 8 or 9 project using Interactive Auto . But I want to implement authentication using JWT or identity , so that whenever I want, I can show the login page inside a modal or elsewhere.( without refresh page or ... )

Because I've tested it before — when using a modal and trying to use SignInManager.SignIn inside the login component, it throws a 'headers are read-only, response has already started ' error and doesn't let it work.

I've seen many websites that show auth modals anywhere without refreshing the page, and it works fine.how to do it ?
