How to retrieve files in violation of a given policy?

[Boston-of-Gilead]

How to access https://security.microsoft.com/cloudapps/policy/file//report?tab=matches&tid= programmatically? I need to get the filenames of everything in violation of a given policy.

I can get the policy using Get-MCASPolicy, but Get-MCASFile and Get-MCASAlerts don't grab what I need because you cannot filter by policy... i.e. Get-MCASAlerts | ? {$_.policy -eq ""}
