Dotaz MySQL, seskupit a poté seřadit podle nejnovějších seskupených s podmínkou

Přidal jsem to do klauzule where a zdá se, že to funguje

WHERE 
'$myid' IN ( senderID ) AND senderdelete = 0 
OR
'$myid' IN ( receiverID ) AND receiverdelete = 0

 $query_messages = mysqli_query($link,"SELECT 
      PreQuery.*,
      m2.message,
      m2.senderID,
