Development and QA teams can use this preview to test the pull request before it's merged into a production or integration branch.
To provide backend support for your preview, Amplify automatically provisions a temporary backend environment that it deletes when the pull request is closed. If you want to specify a dedicated backend environment for your previews, use the
PullRequestEnvironmentName
property.For more information, see Web Previews in the Amazon Amplify Hosting User Guide.
