How to show hidden fields in edit submission?

How can i get the hidden field on the form to show when we receive the submission, I dont want them visible to the student but need them for office use

You can use the "Get form page URL" widget to trigger a conditional logic that will show hidden fields when the submission is in edit mode.

For instance, you can create a condition like this:
If "Get Form Page URL" contains "edit" then show "select fields".
