When a document is printed or download

[mabulail]

Having a trigger to run when a document is printed or download from sharepoint is a very good addition.

This is a very good idea.

Agreed, this would be very useful, because SharePoint online does not allow direct auditing of downloads. Flow could populate a SharePoint list for further analysis using e.g. PowerBi or Excel.
