[Typescript] [Question] example of how to use typescript-angular-client codegen?

As addressed in this old thread: https://github.com/swagger-api/swagger-codegen/issues/3221 I would like to see how you actually use it with a basic example, not just linking another project where it has been done as this is no help at all or explanation of what has been done..

How do I get to view the pet.service.ts pet.ts etc in swagger? I have ran the other example of creating "hello world" with swagger project create, but this is in a .js which again is no help but it works within the swagger editor which was cool...

So may I please get a clear explanation of what do I do with these files as it has not been addressed anywhere I have checked online. Is there more to the set-up? I can't run swagger start typescript-angular-client so do I need more dependencies?

Start with the requested typescript-angular-client flow and the generated pet.service.ts and pet.ts files, then compare it with the existing Swagger Editor hello-world example. Document how to generate, view, set up, and use these files, including whether additional dependencies are required. Done means a basic example clearly explains the setup and usage without relying only on an external project.
