Unable to set page title

[CallumBee]

After trawling though Volt, Livewire and Folio docs I found what i thought was the answer to this but none of these seem to work!

So tried using:

public function rendering(View $view): void
{
     $view->title('Login');
}

But throws an error about not being able to find the $title variable.

then i moved onto:

use Livewire\Attributes\Title;
use Livewire\Component;
 
#[Title('Login')] 
new class extends Component...

That throws an error about unexpected new.

so moved onto:

use Livewire\Attributes\Title;
use Livewire\Component;
 
 
new #[Title('Login')] class extends Component...

That again throws an error about not being able to find the $title variable.

So I moved onto using:

use function Livewire\Volt\{title};
...
title('Login');

Again throws an error about not being able to find the $title variable.

I reset the caches each time I am stumped to what is going on. Has anyone had success with any of these or a way to add the page title?
