I’m working on a web application using Next.js and React.js, and I need to ensure that PDF files are opened within Safe Exam Browser (SEB) rather than standard browsers like Google Chrome. SEB provides a controlled environment for secure online exams, and I want to leverage it to display PDF files securely.

How can I force the PDF links to open in SEB?
How can I verify that requests are coming from SEB in my Next.js server?
