How change the default login path for asp.netcore 3.1

The app is using Azure AD B2C for authentication

services.AddAuthentication(AzureADB2CDefaults.AuthenticationScheme)
                   .AddAzureADB2C(options => { 
                       Configuration.Bind("AzureAdB2C", options);
                   });

by default when a page has the [Authorize()] Attribute it redirects to the Azure AD B2C login page if user is not authenticated.

Instead I want the redirect to go back the application home page. What is the way to accomplish that?

EDIT Attribute created after answer provided. This solved my problem.

public class AuthorizeRedirectAttribute : Attribute, IAuthorizationFilter { public AuthorizeRedirectAttribute() { }

    public void OnAuthorization(AuthorizationFilterContext filterContext)
    {
        if(!filterContext.HttpContext.User.Identity.IsAuthenticated)
        {
            filterContext.Result = new RedirectToPageResult("Landing");
        }
    }
}
