I'm currently working on a leave approval request calendar and ran into some difficulty. I am using this video on vacation request using MS Flow as guide. Is there a way to customize the email generated from "Start an Approval" action within the Start approval when a new item is added? I also tried replacing it with "Send email with option" without success.
I'm receiving a email that states "Start an Approval action failed. Please check the values assigned for the action".
Thank you for your assistance.
