Select2 ajax delay option

For select_advanced fields can we please have a way to set the ajax delay option for select2 via js_options for the field or a filter?

https://select2.org/data-sources/ajax#rate-limiting-requests

I've tried adding it to js_options but it's not working.

array(
    'name' => 'Author',
    'id' => 'post_author',
    'type' => 'user',
    'field_type'  => 'select_advanced',
    'placeholder' => 'Select an Author',
    'query_args'  => array(
        'role' => 'my_custom_role',
        'number' => 10,
    ),
    'js_options' => array(
        'minimumInputLength' => 3, // Require this many characters before triggering the ajax request.
        'ajax' => array(
            'delay' => 10000, // Wait this many milliseconds before triggering the ajax request.
        ),
    ),
),
