How to call child component method?

Question

Vue.js

You need to call a method from a child component if the child component is the same component as the parent.
For example:

<some-component>
  <another-component>
    <some-component></some-component>
  </another-component>
  <another-component>
    <some-component>
      <some-component />
    </some-component>
  </another-component>
<some-component></some-component>
</some-component>

It is necessary that when a component is called in the root some-component - the same method would work for other some-component components that are children of the root some-component.

There was such a question at the interview)
I solved it through ref. (here there is an implementation https://github.com/AlexeyCaTHaR/testAssignment )
It was proposed to forward the method and everything that is needed for this through provide / inject.
There is an option to enumerate vm.$children and, depending on the name of the component, register it in the "pool" of child components and force the method to run
