From SharePoint Online you can trigger a flow by using a link or a button. Sometimes you want to include data with that trigger action. In this article I will show you how to retrieve the email address of the person who clicked the button in a Power Automate flow.
This question from anthonys123:
My thought was to create a flow in PowerAutomate so when a button is pressed it sends a pre-scripted email from the person pressing the button. The directive is to confirm that someone has reviewed the page.
