synchronous usage broken

[gmankab]

Checklist

• I am sure the error is coming from Pyrofork's code and not elsewhere
• I have searched in the issue tracker for similar bug reports, including closed ones
• I ran pip3 install -U git+https://github.com/Mayuri-Chan/pyrofork and reproduced the issue using the latest development version

Description

there is a synchronous useage guide in docs - https://pyrofork.mayuri.my.id/main/topics/synchronous.html

when i run the code it runs, throws no errors, but there are no any sent messages

Steps to reproduce

1. copy code from synchronous usage guide
2. run the code
3. see that message was not sent

Code example

from pyrogram import Client

app = Client("my_account")

with app:
    app.send_message("me", "Hi!")
    print('sent')
