reactjs – How to run a project built on Visual Studio with React components on webOS?

I have installed webOS SDK, CLI and emulator provided at webostv.developer.lge.com/develop/getting-started. I have a react project already created and I want to run it on the emulator, but I really don’t know how to do it. could you give me a hand? I’m sorry but I really don’t have confidence in this topic and I don’t know where to start. Should i create a build with npm run build?

I would be so grateful, yesterday I was practically all day without success. I’m using Visual studio code as my development environment and I’ve also installed the webOS extension. Thanks in advance.
