Jira service project read only textarea field


I need to display a textarea in a service desk project.
I can use a service request and add it to my service site and its shown there, I even tried creating a form and using it on there and that only showed in the preview, when I ran it on the site the contents of the form were not shown.

Im looking for a way to show EULA text and a checkbox on a service request form , but I need the eula text in the issue created from it because that can change in the future, I need the current version of the eula with it so I know what the user signed up for
