How to schedule a python script on Heroku?

Question

Python

I have a parser script on Heroku. Once a day, it starts, parses, sends data to the telegram channel.
I enabled heroku scheduler and configured the start time. But he still asks to drive a team. What is there to write? Here is my Procfile:
bot: python main.py

Is this enough?

heroku run python main.py или просто python main.py?
