XLabs HybridWebView Call Native Method Pushmodalasync?

Hi Guys,

I have a login page (contentpage) and these are a little code block of my page:

_hybridWebView.RegisterNativeFunction ("ShowLoginPage", (input) => {                
                //TODO: IN HERE 
        });

Can i call Navigation.PushModalAsync(new MainContainerPage()) this method in there?

I mean, I want to create login page with cshtml (using portablerazor) and when click sign in button, call the native func and navigate main page.

Thnks.
