Use OAuth to ask for scope permissions immediately after merchants add your app

[zhagan]

I was testing the app in a test store. This is the first time I submitted an APP application, but the email I received said "Use OAuth to ask for scope permissions immediately after merchants add your app", and the video（ this screencast）and method(this method.) was also provided in the email.

However, as a newbie to SHOPIFY, I don't understand the content of this email very well, nor do I understand what the video inside is about.

Can anyone tell me what to do next?
thank you very much

Use OAuth to ask for scope permissions immediately after merchants add your app. Check and troubleshoot your app's OAuth by reinstalling your app on your test store using this method. See this screencast for context on your existing install flow.
