add json file to Angular 12 project that I can read from code, which will be separated after build on web server

I need to add a config json file to angular 12 project, that I could use in my code, and edit on the web server so it would be dynamic. e.g: { "api1": "[login to view URL]", "api2": "[login to view URL]", } The goal of the project is to tell me how to do it.
