Ability to control a plugin from outside (e.g. from an extension). #1282

The problem I am facing
I'm implementing a Mention-like Extension using the Suggestion-Plugin and would like to access its internal state and/or trigger its methods. In my case i would like to use an Escape-KeyboardShortCut to close the Suggestion if it's active.

The solution I would like
A way to access the internal state and/or methods of the plugin.

Alternatives I have considered
Implementing the functionality inside the render function of the Suggestion – but i think that function should really only be handling the visual representation of the Suggestion.

Additional context
Internal state is accessible on state.suggestion$, but i don't think that it is meant to be accessed directly (https://github.com/ueberdosis/tiptap/blob/main/packages/suggestion/src/suggestion.ts#L130).

addKeyboardShortcuts () {
  return {
    Escape: () => this.editor.commands.command(({ tr, state }) => {
      // How to access `active` on the internal state? 
      // How to 'close' the suggestion if active?
    }),
  }
},
