How can I run an async function using the schedule library?

Question

I'm writing a discord bot using discord.py rewrite, and I want to run a function every day at a certain time. I'm not experienced with async functions at all and I can't figure out how to run one without using "await." This is only a piece of my code which is why some things may not be defined.

async def send_channel():
    try:
        await active_channel.send('daily text here')
    except Exception:
        active_channel_id = None
        active_channel = None

async def timer():
    while True:
        schedule.run_pending()
        await asyncio.sleep(3)
        schedule.every().day.at("21:57").do(await send_channel())

@bot.event
async def on_ready():
    print("Logged in as")
    print(bot.user.name)
    print(bot.user.id)
    print("------")

    bot.loop.create_task(timer())

Using the schedule.every().day.at("00:00").do() function, I get this error when I put await send_channel() in the paramaters of .do():

self.job_func = functools.partial(job_func, *args, **kwargs) TypeError: the first argument must be callable

But when I don't use await, and I just have send_channel() as parameters, I get this error:

RuntimeWarning: coroutine 'send_channel' was never awaited

I'm not super good at programming so if someone could try to dumb it down for me that would be awesome.

Thanks

The built-in solution to this in discord.py is to use the discord.ext.tasks extension. This lets you register a task to be called repeatedly at a specific interval. When the bots start, we'll delay the start of the loop until the target time, then run the task every 24 hours:

import asyncio
from discord.ext import commands, tasks
from datetime import datetime, timedelta

bot = commands.Bot("!")

@tasks.loop(hours=24)
async def my_task():
    ...

@my_task.before_loop
async def before_my_task():
    hour = 21
    minute = 57
    await bot.wait_until_ready()
    now = datetime.now()
    future = datetime.datetime(now.year, now.month, now.day, hour, minute)
    if now.hour >= hour and now.minute > minute:
        future += timedelta(days=1)
    await asyncio.sleep((future-now).seconds)

my_task.start()
