Open a paragraph programmatically

I have a paragraph contact nested inside another paragraph occurrence.

In the widget settings the paragraph contact is defined to be collapsed by default (edit_mode = closed).

I want the contact paragraph only to be open when creating the content and only on the first occurrence.

How can this be achieved?

Thanks in advance.

I achieved what I wanted to to by letting the contact field open by default (edit_mode = open) and then in an hook_form_node_form_alter remove the contact form with this code

// Collapse contact field except for the first occurence.
foreach ($form['field_occurence']['widget'] as $delta => $field) {
  if (is_int($delta) && $delta != 0 && isset($field['subform']['field_contact']['widget']['0']['subform']['#type'])) {
    unset($form['field_occurence']['widget'][$delta]['subform']['field_contact']['widget']['0']);
  }
}

I guess there is a cleaner way but form the moment that does the trick.
