Could you please consider adding a customizable tooltip (ⓘ) beside each request form field, as illustrated in the image? Requestors could simply hover over the icon to view a short guide on what information to enter.

Although instructional text is already available, a tooltip would keep the guidance accessible even if the requestor overwrites or deletes that text while completing the form. The tooltip instructions would be managed by administrators and could not be removed by requestors, helping ensure clearer guidance and more accurate submissions.
