TypeError: unsupported operand type(s) for +: 'datetime.datetime' and 'int'

    if msg.date >= data[user_id]['timestamp'] + flt.data:
                   ~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~
TypeError: unsupported operand type(s) for +: 'datetime.datetime' and 'int'

can be fixed by
if msg.date >= data[user_id]['timestamp'] + timedelta(seconds=flt.data):
on line 24 on cooldown.py
and on line 3
from datetime import datetime, timedelta

and you can change the task function to this for nice animation

async def task(msg, warn = False, sec = None):
    if warn:
        user = msg.from_user
        ids = await msg.reply(f"Sorry {user.mention}, you're in cooldown now, wait for `{sec}`s to use command again..")
        for i in range(sec):
            
            await ids.edit(f"Sorry {user.mention}, you're in cooldown now, wait for `{sec-(i+1)}`s to use command again..")
            await asyncio.sleep(1)

        
        await ids.edit(f"Alright {user.mention}, your cooldown is over you can command again.")
        await asyncio.sleep(3)
        await ids.delete()
