How can one correctly access the provides property using type definitions through a directive?

[royalknight56]

I'd like to get the provides property within a custom Vue directive:

const vDragable: Directive = {
  mounted(el, binding) {
    const foo= (binding.instance?.$ as any).provides.foo;
  }
};

I've noticed that the provides property in ComponentInternalInstance is marked as internal.

Could you please explain the rationale behind this? Thank you.
