Hey All!
We're in the process of creating a react embedded app which uses polaris actions like contextual save bar etc so we cannot develop directly on the localhost url but instead have to go through the mystore.myshopify.com route to make it work.
Putting in https://localhost as the App Url works fine as it opens up the local app inside the admin area of mystore.myshopify.com however what happens once the app is in production? is there a way to add a development app url which opens the localhost URL while developing or the best workflow would be to create a new app just for testing purposes?
