How to make a cooldown per team in discord.py?

Question

Python

I have my code:

@commands.command(
        aliases=['награда']
    )
    async def timely(self,ctx):
        abalance = self.collection.find_one({"_id": ctx.author.id})["balance"]
        self.collection.update_one({"_id": ctx.author.id},
            {"$set": {"balance": abalance + 30}})

        emb = discord.Embed(
            title='Временная награда',
            description=f'__{ctx.author.mention}__, вы получили свои 30 осколков!\n Приходите через 12 часов.'
        )
        emb.set_thumbnail(url=ctx.author.avatar_url)
        await ctx.send(embed=emb)

(PS I use pymongo)
And I would like to cd 12 hours on it. And if the user writes it earlier, then he was given an error and wrote how much was left before receiving the reward.
(I know how to make a crutch, but I want to do it normally and adequately).
I ask for proper help.
