-- Access Hash : For more security, Telegram requires you to provide the specific `access_hash` for chats, files and other resources before interacting with them (not required for a simple `Chat`). This is like showing a pass that proves you are entitled to access it. You obtain this hash when you first gain access to a resource and occasionnally later when some events about this resource are happening or if you query the API. You should remember this hash if you want to access that resource later.
