I am trying to build a Flow for a classroom device that sends out emails when a user presses a help button. However, the hardware does not allow me to restrict the frequency on how often the button will trigger an email. I created a flow that will take the email with a certain subject and pass it along a HTTP call to our ticketing system, marks the email as read, and then moves it to another folder. However, it will create duplicate tickets if the button was pressed more than once. I am trying to find a way to once the email arrives to the mailbox, it will look in another folder within a certain timeframe (within 30mins) and if does it will ignore the triggered email and end the flow. Otherwise, it will continue processing the email through my flow.
