Adding builtin Tiptap extensions

[IlaySkutelsky]

Hi! Thank you for the work on this awesome library.
I want to include the builtin Tiptap Mention extension through the config file.
Even before touching the custom JS and CSS files, I just need to understand how to register it in the config file.
I tried:
'extensions' => [ new \Tiptap\Nodes\Mention(), ] ... 'extensions' => [ 'Mention', ],
But both threw errors. Did anyone managed to do this? Or can anyone point me to the direction I should take here?

The extensions path in the config is expecting a Vite path for the compiled js file.
