Look at the top of the I-797 Notice of Action, approval notice on Nov 10th, you may see,

THIS NOTICE DOES NOT GRANT ANY IMMIGRATION STATUS OR BENEFIT.

AND also you may see somewhere in the approval notice it will say your travel document will be mailed to you separately and will show the validity of the document and any travel conditions.

That means you can't leave US with approval notice and must have I-512L document (your pic on it).
