It's macOS 26.1 My main question is if Apple has any tips on best practices about intercepting SAML authentication requests and how to elegantly pass the assertions back to the browser. The way I see is that by redirecting the assertion to the browser, the application ends up posting the SAML response twice - one on the extension and another on the browser.
