Young catchers who are attempting to frame pitches, often try to frame pitches which are completely outside of the strike zone. It’s a nice thought but not practical. The umpire will not be fooled by you dragging an errant pitch back to the strike zone.
The correct thing to do is to catch it and send it back to the pitcher.
Moving the ball with an obvious movement to make it appear to be a strike can alienate an umpire and can hurt a pitcher later on in the game. This is a catching habit that needs to be avoided at all costs.
The chances of you fooling an umpire are pretty slim and the chances of you losing strike zone credibility with the umpire is pretty high so pulling pitches back in to the strike zone more than a few inches should be discouraged.
So, if its a strike or close enough to be debatable, frame it properly with correct glove positioning techniques. If it’s not a strike or borderline material, catch it and send it back without trying to oversell it.
One pitch in a game is all it takes to change the final score on occasion and with umpire credibility established you just might buy your team a borderline strike at a critical time so let’s keep the framing where it belongs, on quality pitches only.
