 Writing the library logs to the Console is the default behavior of the `WTelegram.Helpers.Log` delegate.  
 You can change the delegate with the `+=` operator to **also** write them somewhere else, or with the `=` operator to prevent them from being printed to screen and instead write them somewhere (file, logger, ...).

 Having only the ID is **not enough**: An `access_hash` is required by Telegram when dealing with a channel, user, photo, document, etc...  
 This serves as a proof that the logged-in user is entitled to access it (otherwise, anybody with the ID could access it)
