I am using flow to launch flows from sharepoint as well as from PowerApps, from sharepoint it works perfectly and it sends emails from the mailbox of the person who created the flow itself, however when I use Flow.Run action in PowerApps to call a flow, and use Send email action, it uses the current user who was signed into PowerApps to send the email, so users are getting emails from themselves. Is there a way to change this behavior? Anything I need to do from the PowerApps side?
