I have a column in a sharepoint list that has a future time based on specific SLA's. How would I create a flow to send an email when that time is reached. Example) I have a request that's critical, which means it has an SLA of 2 hours. I have the column set to make a timestamp exactly 1 hour after the request is submitted. I need to send an email reminder when the current time reaches that 1 hour timestamp.
