I get an error when combining telethon and tkinter

Question

I was trying to make a mixed application with tkinter and telethon, but it gives an error, it should work as logic, but I could not find where the problem is.

here is the code

from tkinter import *
from telethon import events, utils, TelegramClient
import asyncio

window = Tk()
window.geometry('600x600')
window.title("###")


api_id = ###########3
api_hash = '###'

client = TelegramClient('anon', api_id, api_hash)

async def main():  
   await client.send_message("me", f'hi')
   await asyncio.sleep(delay=1)
   asyncio.run(main())

butonq = Button(text="click", fg="black", bg = "white", command=main)
butonq.pack()

window.mainloop()

Logically it should work but I get an error like this

C:\Users\yegen\AppData\Local\Programs\Python\Python39\lib\tkinter\__init__.py:1429: RuntimeWarning: coroutine 'main' was never awaited
 self.tk.mainloop(n)
RuntimeWarning: Enable tracemalloc to get the object allocation traceback

Can you help me solve the problem?. Thanks
