Running Biometric Integration by Cron job

Please,I’m curious as to how to write code on file to run python -c ‘from erpnext_sync import main; main()’ by using a Cron job, which I’ve tried writing myself but the program doesn’t work.

That I am trying to write is

“cron”: {
“0/30 * * * *”: [
“erpnext.erpnext_integrations.[folder.file].python3 -c ‘from push_to_erpnext import main; main()’”

Have you found any solution for this issue, please let me know
thank you
