Policy in screen

I wanted to use policy, but I always get 403 THIS ACTION IS UNAUTHORIZED.

Route::screen('/chat/{chat}', ChatScreen::class)
    ->can('view', 'chat')
    ->name('platform.chat');

class ChatPolicy
{
    public function view(User $user, Chat $chat): bool
    {
        return true;
    }
}

But if you use policies in the screen itself, then everything works

class ChatScreen extends Screen
{
    public function query(Chat $chat): iterable
    {
        if($chat->exists){
            $this->authorize('view', $chat);
        }
        ...
    }
...
