pass async function to thread python

Question

I am building a Discord bot and most of it is event based. Once the bot is ready, I want to have a thread that, while the bot is alive, sometimes writes "hi" in chat and then sleeps for 2 minutes. Code:

async def on_ready(self):
    t = threading.Thread(target=self.say_hi)
    t.start()

async def say_hi(self):
    while True:
        chance = random.randint(0, 101)

        if chance <= 25:
            await self.channel.send('hi')
        time.sleep(60 * 2)

Problem is that I get different errors. RuntimeWarning: Enable tracemalloc to get the object allocation traceback in this case. I tried following this somewhat related answer editing the code in this way:

def say_hi(self):
    loop = asyncio.new_event_loop()
    asyncio.set_event_loop(loop)

    loop.run_until_complete(self.say_hi_aux())
    loop.close()

async def say_hi_aux(self):
    while True:
        chance = random.randint(0, 101)

        if chance <= 25:
            await self.channel.send('hi')
        await asyncio.sleep(60 * 2)

But the resulting error is RuntimeError: Timeout context manager should be used inside a task on loop.run_until_complete() method.

I don't know what's wrong with either solution

@JoshuaNixon didn't mention it, but i tried that too. the error is the same as the latter. — davide m., Mar 20 '20 at 22:54
For scheduling stuff in asyncio I used https://phoolish-philomath.com/asynchronous-task-scheduling-in-python.html as a starting point — Joshua Nixon, Mar 20 '20 at 22:59
@JoshuaNixon I cannot follow the same pattern because things are slightly different, though no result. — davide m., Mar 21 '20 at 09:38
