I am seeking assistance with an issue related to Microsoft's app.useCookiePolicy() and my Umbraco Project using version 12

To provide some context, I have implemented Microsoft's app.useCookiePolicy() in my application, which manages cookie policies effectively. The problem arises when I attempt to use this functionality to enable login access to my cloud backoffice. Instead of gaining access, the URL gets stuck in a perpetual login loop, and displays a blank screen.

I suspect there might be a conflict between app.useCookiePolicy() and the cloud backoffice's authentication mechanism, but I can't pinpoint the exact cause.

If anyone has encountered a similar issue or has expertise with Microsoft's app.useCookiePolicy() and cloud backoffice logins, I would greatly appreciate your insights and guidance on resolving this problem. Additionally, if you could provide step by step instructions on properly integrating app.useCookiePolicy() , it would be greatly appriciated :)

my startup.cs code:

using Microsoft.AspNetCore.Rewrite;
