How to handle dynamic port changes for backend minimal API in blazor server project

[nssidhu]

I am using Blazor Server with .NET 9 and Aspire 9.1.
I my Blazor Server, i also have Minimal exposed.
there is a Client side JavaScript that needs to call the backend minimal API.
Since Aspire assigns port randomly to minimal api, i am stuck with not able to call my back-end api.
Also since the port number changes, i am also having hard time applying CORS on my backend api.

How can i dynamically send the URL from server for my minimal api to my JavaScript dynamically ?
