If the 'Items to review' window isn't already open at the bottom of your screen, click the black bar to open it.
Hover over the item you want to create and click Review. You will be taken to the Submittal Builder in the Submittals tool in Procore. Note: If you don't see the submittal item in the 'Items to review' window at the bottom of your screen, you may need to generate the submittal first. Or, the item was already reviewed or deleted.
