Co Authoring with different positions

I found a correct answer. I ended by adding custom fields (translators, reviewers …) with the ACF plugin. Example:

    Field Label: Translators
    Field Name: translators
    Field type: Relational (user)
    Field Type: multi-select
    ..

However, this will make the table wp_postmeta very huge, as my website will contain a large number of posts.
