I really like the way Jaylen can switch hands and finish left on his drives when he needs to. Tatum still kind of angles his body sideways in the same situation to get side on because he won't (or can't) use his left hand effectively.
So during our covid lockdown in Melbourne, we had 1hr/day we could go outside for workout purposes.
Every day I went out (4 a week) I went to an empty basketball court and shot the ball.
Every miss, I rebounded with left, spun to my left hand, and either laid it up with left, or took 1 left-handed dribble, left handed gather and layup.
Until I could do the gathering without even touching the ball with my right hand.
It's been super useful in competition play and I now prefer to drive to my left hand 
End of random game-break story.
Used to do the back and forth drill. Take the ball shoot it with your right from the right side. After making it, grab ball, jump left, shoot it with your left hand. Grab ball. Rinse and repeat for 10 minutes, every day . By high school I could finish with both hands quite easily
