What is equivalent to `MapSpaFallbackRoute` for ASP.NET Core 3.0 endpoints?

In ASP.NET Core 3.0 extension method MapFallbackToController has same functionality to MapSpaFallbackRoute extension method.

public void Configure(IApplicationBuilder app)
{
    app.UseRouting();
    app.UseEndpoints(endpoints =>
    {
        endpoints.MapControllerRoute(
            name: "default",
            pattern: "{controller=Home}/{action=Index}/{id?}");

        endpoints.MapFallbackToController("Index", "Home");
    });
}
