Hide Content With MS Word Checkboxes

I would like to check a content control checkbox and have it only show some text content when the box is checked.

I have attempted to do this with IF statements and bookmarks, but I have not been able to get it to do what I want.

Even just trying to reference the checkbox in Word is proving to be difficult:

{IF check = ☒ "CHECKED" "UNCHECKED"} 

Where the title and tag of the checkbox are 'check', and the ☒ is a content control checkbox.

Any steering in the right direction would be helpful! I am trying to avoid using VBA.
