How to access paragraph fields from a webform's form?

Question

I have a webform (contact_info) which is attached to a paragraph's field (field_contact_info). The paragraph has other fields as well.

I implemented hook_form_alter() to change some attributes inside the webform's form.

Is there any way to access the values of other paragraph fields value in hook_form_alter()?

I can pass them inside the webform object, but those aren't available in hook_form_alter() or the form array.

Any help on this?

This question is answered by @hudri

inside the hook_form_alter() get the entity first:

if ($form_state->getFormObject() instanceof \Drupal\Core\Entity\EntityFormInterface) {
  $entity = $form_state->getFormObject()->getEntity();
}

Then get the parent paragraph using this

$entity->getSourceEntity()

This will return the paragraph instance with all the fields.
