Is it possible to create a custom action that extends from Filament action?

[appdev112]

I want to create an additional extension with a custom button for the tiptap editor that opens modals from the Filament action component just like the link action, oembed action, media, etc.

I read on the documentation only media, edit media, link, grid builder and oembed actions that are customizable using Filament action.

Is it possible to create my own feature for this?

I have tried using the custom extension with JS, but how to make this JS have livewire and filament functionality?

Here's what I want to achieve:

1. I have a few shortcodes that can be added to the tiptap editor.
2. I want to add a custom button to the tiptap editor that opens a modal.
3. The modal form fields will be dynamic depending on the selected shortcode (this is the reason why I want to use the filament form component for this).
4. Once all the fields are filled, the shortcode will be inserted into the editor.

Wouldn't that just be a custom block?
