if matter of hitting "approve", create cloud code function "approve article" called admin tapping approve button. function sets approve status , calls function (still in cloud code) sending push message user.

alternatively approve button can change status , save document, , aftersave() function in cloud code can handle push. less clear, though, since aftersave() function called when record saved, , need check status , send push if article has been approved.
