How to load the previous revision of a paragraph?

I can load paragraphes of a nodes field using

$paragraphs = $node->get('my_field')->referencedEntities()

In hook_node_update I could load the previous paragraphes using

$paragraphs = $node->original->get('my_field')->referencedEntities()

But instead I would like to load the previews paragraph from their id, somethings like:

$paragraphs = $node->get('my_field')->referencedEntities()

foreach ($paragraphs as $key => $paragraph) {
  // getRevisionIDs is pseudo code and does not exist
  $revisionIds = getRevisionIDs($paragraph['entityKeys]['id'])
  $previewParagraph = \Drupal::entityTypeManager()->getStorage('paragraph')->loadRevision($revisionIds[1])
}
