How to intergrate telethon script into my event loop?

I have two bots, one is using pydle for IRC, like:

async def start_ircbot ():
    try:
        client = MyOwnBot(NICK, 
                       realname=REALNAME,
                       sasl_username=SASL_USERNAME,
                       sasl_password=SASL_PASSWORD,
                       sasl_identity=SASL_IDENTITY,)

        loop = asyncio.get_event_loop()
        asyncio.ensure_future(client.connect(HOST, PORT, tls=True, tls_verify=False), loop=loop)
        loop.run_forever()
        loop.close()
    except Exception as e:
        print (e)

and another is using telethon for Telegram:

@client.on(events.NewMessage)
async def my_event_handler(event):
    ...

async def start_client ():
    print ("Telegram monitor started...")
    await client.start()
    await client.run_until_disconnected()

Both of them work without problem separately.

Now, I want to integrate both of them, I tried to launch both of them in my main function like this,

import Notifier

...

async def main():
    await asyncio.gather (Notifier.start_client (), start_ircbot ())

asyncio.run(main())

It starts without issue but my_event_handler seems never to get new messages. If I swap the order of functions:

await asyncio.gather (start_ircbot (), Notifier.start_client ())

The script will be stuck at launching, I suspect it has to be something within events loops and tried some different methods but without luck, could anyone shed light on this for me?
