I have a python application and I need it to be run as a service, I tried many methods and I was advised to make it as systemd service

I searched and tried some code

here is my unit code

[Unit]
Description=Airnotifier Service
After=network.target[Service]
Type=idle
Restart=on-failure
User=root
ExecStart=python3 /home/airnotifier/airnotifier/app.py[Install]
WantedBy=multi-user.target

and then I run the following commands

sudo systemctl daemon-reload
sudo systemctl enable airnotifier.service
sudo systemctl start airnotifier.service
sudo systemctl status airnotifier.service

the service does not run and I am getting this errors

airnotifier@airnotifier:~$ sudo systemctl status airnotifier.service
● airnotifier.service - Airnotifier ServiceLoaded: loaded (/lib/systemd/system/airnotifier.service; enabled; vendor preset: enabled)Active: failed (Result: exit-code) since Mon 2023-01-09 14:07:38 UTC; 1s agoProcess: 2072 ExecStart=/usr/bin/python3 /home/airnotifier/airnotifier/app.py (code=exited, status=1/FAILURE)Main PID: 2072 (code=exited, status=1/FAILURE)Jan 09 14:07:38 airnotifier systemd[1]: airnotifier.service: Scheduled restart job, restart counter is at 5.

This is the code that works with me

WorkingDirectory=/home/airnotifier/airnotifier
ExecStart=python3 app.py
Restart=always
