I would find even more use for PowerApps if I could program some voice commands for Cortana/Siri/GoogleNow to understand.
"Hey Cortana,
Add a new User [Name] to the User [Entity]."
Flow -> CDM -> Add Object to User Entity -> User = Name
Flow -> When an object is created in [Entity] -> Send a Push notification
Cortana should be prioritized first above the other voice assistants.
Adding @archanan to confirm status pls.
