I found this solution in another forum, I think that is what you were looking for. I post it so it can be useful for other users

        DB::select('
            SELECT t1.*
            FROM messages AS t1
            INNER JOIN
            (
                SELECT
                    LEAST(sender_id, recipient_id) AS user_id,
                    GREATEST(sender_id, recipient_id) AS recipient_id,
                    MAX(id) AS max_id
                FROM messages
                GROUP BY
                    LEAST(sender_id, recipient_id),
                    GREATEST(sender_id, recipient_id)
            ) AS t2
                ON LEAST(t1.sender_id, t1.recipient_id) = t2.sender_id AND
                   GREATEST(t1.sender_id, t1.recipient_id) = t2.recipient_id AND
                   t1.id = t2.max_id
                WHERE t1.sender_id = ? OR t1.recipient_id = ?
            ', [auth()->guard('api')->user()->id, auth()->guard('api')->user()->id]);
