"editor.sideMenu" is undefined in @blocknote/core (Vanilla JS Setup Guide is broken)

[vadolasi]

What’s broken?

I am trying to implement BlockNote in a Svelte project (using the Vanilla JS approach since there is no official Svelte wrapper). I followed the official "Getting Started - With Vanilla JS" documentation.

The documentation explicitly instructs to access editor.sideMenu to create custom UI elements:

// From the docs:
editor.sideMenu.onUpdate((sideMenuState) => {
   // ... implementation
});

However, in the latest version of @blocknote/core, the sideMenu property (and all other UI elements) does not exist on the BlockNoteEditor instance.

What did you expect to happen?
