    # "me" is a user object. You can pretty-print
    # any Telegram object with the "stringify" method:

    # When you print something, you see a representation of it.
    # You can access all attributes of Telegram objects with
    # the dot operator. For example, to get the username:
    username = me.username
    print(username)
    print(me.phone)

    for mess in messa:
        print(mess.message)

    # entity = await client.get_entity(username)

    # await client.get_dialogs()

    # Are they participant of some group? Get them.
    # await client.get_participants('https://t.me/rbc_news')

    # Is the entity the original sender of a forwarded message? Get it.
    # await client.get_messages('https://t.me/rbc_news', 10)
