I'm currently working on a worflow that will automatically enter a PTO in the shared calendar for the person who texts "out sick" to our phone number. I made an sms workflow that triggers after record is created, and in the actions panel I added a "create record > PTO" action with the settings you can see in the screenshot. If I hardcode in an assigned user, it runs just fine and does what I need. But I don't know how to set the assigned user dynamically. How can I achieve this?
