Make URL configurable by reading from appsettings.json file in a blazor page

I have a blazor project and I wanted to make my page URL configurable by reading from appsettings.json file. I have tried the following

Login.razor page

@page "LOGIN_URL"

appsettings.json file

"LOGIN_URL": "496436/login"

This is what I wanted. But I am not able to find a solution for the same and according to the values in appsettings.json, the url should automatically change or reflect in Login page.
