Hi @EllaBurgun,
For clarification, is your "student support page"/:support hub" in Canvas? If so, you won't easily be able to add script content, as it's not allowed in Canvas (most likely for security reasons). You can see the Canvas HTML Editor Allowlist - Instructure Community article for information about what HTML is explicitly allowed in Canvas. If you're a Canvas administrator, you may be able to use the theme editor to insert some content into some areas via javascript/css, but that is usually intended for global things, not something specific to a specific course (or specific page in a course).
Hope this helps a bit!
