Open react native project in xcode

I'm sure I'm missing something simple. I have a React Native project working and I'm attempting to get it on the app stores. Following those instructions, after I have created my provisioning profile in the Apple Developer Dashboard, it says to double click the developer provisioning profile to launch xcode. It's these instructions exactly:

Now find the files you just downloaded on your computer, and double-click each of them in turn, causing Xcode to launch. Verify the profiles are there by opening a project or starting a new one for this test.

So I double-click my file, and xcode does launch but no windows open up. I do not have an xcode project for my react native app so I have nothing to open. There is no menus for 'build settings' or 'general' so I'm not sure how to proceed.

For reference, here is my react native directory structure:

my_project/
    .expo/
    assets/
    node_modules/
    src/
    .bablerc
    .gitignore
    App.js
    app.json
    package-lock.json
    package.json
    README.md

Did I miss a step somewhere? How do I get an xcode project from this?
