How to properly add a service to systemd with python bot on CentOS?

Question

linux

Hi all! During the holidays, I try to take my first steps in telegram bots. I want to run my bot on a virtual machine. I found a method to start a bot as a separate service in Linux, write a config file and get an error. The service does not start.

Here is the bot.service file config:

[Unit]
Description=Telegram bot 'TEST'
After=syslog.target
After=network.target

[Service]
Type=simple
User=root
WorkingDirectory=/root/Downloads/bot/
ExecStart=/root/Downloads/bot/env/bin /python3 /root/Downloads/bot/main.py
RestartSec=10
Restart=always

[Install]
WantedBy=multi-user.target

When you enter the systemctl status bot command, the following is output:

bot.service - Telegram bot 'TEST'
Loaded: loaded (/etc/systemd/system/bot.service; enabled; vendor preset: disabled)
Active: activating (auto-restart) (Result: exit-code) since Thu 2021- 06-03 22:51:09 +05; 651ms ago
Process: 9504 ExecStart=/root/Downloads/bot/env/bin/python3 /root/Downloads/bot/main.py (code=exited, status=1/FAILURE)
Main PID: 9504 (code=exited, status =1/FAILURE)

The project itself and its directories:

-rw-r--r--. 1 root root 1550 Jun 2 20:38 buttons.py
drwxr-xr-x. 2 root root 6 Jun 2 20:41 Documents ===>

-rw-r--r--. 1 root root 478 Jun 2 20:39 states.py

Please help, what is the problem here. Sincerely.
