Python3 Discord Bot on Glitch

I’m writing a bot with python3 in glitch. My wish is to renew the bot every time you change letters (as in discord.js). it opens if I type it from the console.

files and contents in my project:

main.py - There is no problem in the codes inside, it works normally.
requirements.txt - ‘discord.py’
start.sh - ‘python3 main.py’
and other files of the bot [no problem, running (config.json etc.)]
