How to send a complex object to a Razor page

Question

I am working on an ASP.NET Core 6.0 Identity project. I want to pass an ApplicationUser object to the LoginWith2fs.cshtml page from the Login.cshtml page.

This is my code - login page:

return RedirectToPage("./LoginWith2fa", new 
                                        { 
                                            UserSent = user, 
                                            ReturnUrl = returnUrl, 
                                            RememberMe = Input.RememberMe 
                                        });

Code in LoginWith2fa page:

// Created this property in the LoginWith2fa page. Not sure this is needed or not
public ApplicationUser UserSent { get; set; }

public async Task<IActionResult> OnGetAsync(ApplicationUser UserSent, bool rememberMe, string returnUrl = null)
{
    // More code here
    // the  ApplicationUser object has null values in its properties such as username and email
    // However the rememberMe and returnUrl variables have correct values
}
