[Hummingbird Pro] Clear Cache Via Cron

Hello, I'm looking for assistance in trying to set up a cron job to clear my hummingbird cache automatically every week. Live support sent me a link to https://premium.wpmudev.org/docs/wpmu-dev-plugins/hummingbird-api-docs/ but I'm still none the wiser what to do with any of that information. Could you provide me an example url to run which would clear the hummingbird cache, please. Ill then add it to a cron job on my server

Thank you
