Content missing on Use existing AWS resources

**Describe the content issue**:
A clear and concise description of what the content issue is. Is there content missing or is there incorrect content?

>When you are not using Amplify CLI, adding existing Amazon S3 bucket to your application may require configuring bucket access permissions. e.g. Enabling read/write access to the Cognito user pool that you are using with the Amplify Auth category.

`the Cognito user pool` is may missing text, Correct text is `the Cognito identity pool` or `the Cognito user or identity pool`.

On AWS blog text is may correct, that is wrote `Identity Pool`.
