Post author field supported?

Is a Meta Box field for the post author to replace the default WP author field supported?

If so, what is needed?

I've tried setting the id to author and post_author based on this topic (and the linked tutorial) https://metabox.io/support/topic/can-a-default-wp-post-table-field-be-added-to-a-metabox-tab-ie-post_author/

but the Meta Box field is not populating with a saved post's author.

Here is my field:

array(
    'name' => 'Author',
    'id' => 'author',
    'type' => 'user',
    'field_type'  => 'select_advanced',
    'placeholder' => '-- Select Author --',
    'query_args'  => array(
    'role' => 'my_custom_role',
        'number' => 10,
    ),
    'js_options' => array(
        'minimumInputLength' => 3,
    ),
),
