In What If...? (2021), the main character is "The Watcher", a cosmic being with the power to see all universes. He shows us various universes and finally
breaks his vow to not interfere in order to save the multiverse from Ultron-Vision.
However, in the comics, a character also referred to as "The Watcher" is Uatu the Watcher. Is the Watcher in What If...? actually Uatu the Watcher canonically? I'm looking for a reference in the show that shows this, or out-of-universe confirmation by someone in authority to say such things.
