In the integrated browser, I can't view a github pages site that is in my EMU org. It is asking me to authenticate and since I am a Microsoft employee, it is not allowing me to authenticate and is saying my device is not registered. I am using my employee laptop and can access everything from my normal browser. Is there a way for it to just leverage the same credentials or something so I can use the integrated browser?

Start by reproducing the authentication failure in the integrated browser on the /chat path with a GitHub Pages site in an EMU organization, using the reported app version and macOS environment. Compare it with access from the normal browser; done means the integrated browser can use the existing credentials without the device-registration error, or the limitation is clearly documented.
