How to hide a icon using JavaScript?

[ksklein]

Have a icon (gray circle with x on it) on a page that needs to be hidden so Instructors cannot delete a course section from our learning management system. I've attached a screenshot of the element but I don't know how to code this in our JavaScript file to hide it when the page is rendered.

there are three possible ways:
- delete the Element
- hide the Element (via display: none)
- remove the Element’s event listener
