How to edit thing of type EmailBody

Hi bubblers,

I have a very basic question. I created a thing of type “EmailBody” under Data. Now I can’t figure out how to set a default value to it, or edit the value with workflows.

My intention is to use that to pass into the outlook plugin to send a custom email from within the web app.

Sorry if this is too basic. I tried looking through the forums and references but couldn’t find the answer. Thanks!
