Under actions, select the Create Pre-Release action on the left. Click the Run workflow dropdown and enter the full commit hash for the commit pushed into Production. Select Run workflow, and after a few seconds, the action will run.
This action publishes a Pre-release. Select the newly created pre-release and auto-generate the release notes. Auto-generating the notes will add a What's Changed section listing each commit since the last release and a link to the full changelog.
The release engineer will fill in a high level summary of the changes that were released by replacing TODO: insert summary. Once done writing the summary, uncheck Set as a pre-release and check Set as the latest release.
