Laravel dusk assert flash message

I have following flash message generated on my page

flash('Success message')->success();

Trying to assert through

->assertSee('Success message');

With no luck

<div class="alert
                    alert-success
                    " role="alert">              
            Success message
        </div>

I will always get

Did not see expected text [Success message] within element [body].
Failed asserting that false is true.

Despite the fact the message is in the body

What am I doing wrong?

Thanks
