Your question is TLS 1.3 and Proxy Interception. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Describe the advances of TLS 1.3 over previous versions of TLS/SSL, how a browser retrieves web pages, and how a proxy can perform man-in-the-middle interception. Also, what policy devices have you used (firewall, proxy, DLP, etc) and what are the pros and cons of each?
Organize your response as a practical technical walkthrough. Cover protocol changes, the browser-to-origin request path, certificate-based interception and trust requirements, and operational trade-offs among policy enforcement points. Distinguish technical capabilities from products you have personally used.
