File Prevalence API call

We have Microsoft Defender ATP and Office ATP integrated. In MD ATP when I view a file page, I can see the prevalence of the file both on workstations and in mailboxes. If I click on the mailbox section it takes me to Office ATP.

MD ATP has an API call where I can get the prevalence of a file, but it only returns the machine prevalence in the results. Is there a similar API call for Office ATP that can give me the prevalence in mailboxes?

Thanks,
