title: forward message to super group with telethon
body: <p>Recently I wrote code that should forward every message from a certain user to all groups that I joined but it doesn't.
  Here my code:</p>
  
  <pre><code>        for message in client.iter_messages('aliakhtari78'):
          try:
              dialogs = client.get_dialogs()
              for dialog in dialogs:
                  id_chat = dialog.message.to_id.channel_id
                  entity = client.get_entity(id_chat)
                  client.forward_messages(
                      entity,  # to which entity you are forwarding the messages
                      message.id,  # the IDs of the messages (or message) to forward
                      'somebody'  # who sent the messages?
                  )
  
          except:
              pass
  </code></pre>
  
  <p>in this code first I take every message which send to me by <strong>'aliakhtari78'</strong> and then get entity of the groups that I joined to and in the end it should forward the message to all groups but it doesn't, I check my code and replace the entity with a user entity and it worked and I know the problem is because of entity, but I cant find out what is my problem.
    <strong>In addition, I'm sorry for writing mistakes in my question.</strong></p>
