Automate deletion of all activity from Facebook Pages 'activity log'

I have a Facebook page, and need to delete all history, where possible, from the https://www.facebook.com/<page name>/allactivity URL

There's data going as far back as 2013, so would like to have a script automate the process. I'm currently clicking the buttons one by one.

Open to which technology used to complete this task... whether it's javascript within the console, or using another piece of software. As long as it's automated, I'm happy! :)
