What is the path to the PHP file to run a CBSubs Mailer Cron Job?

I contacted my host in order to setup a cron job to run the cbsubs mailer at set intervals.
My host told me that the URL provided in the automation settings would not work and that I need a direct link to a php file or some script file.

Would using this reference link work to run a CBSubs mailer cron job?

components/com_comprofiler/plugin/user/plug_cbpaidsubscriptions/plugin/cbsubsmailer/cbsubs.mailer.php

Please advise on how to setup the cron job referencing a script file or another solution.

Thanks

The URLs are provided in backend within CBSubs > Mailer > Automation Settings.
