Hello Francois!
I'm happy to help! I'm having a difficult time understanding exactly what you're looking to do on the slide. However, I did notice that the animation you added is a Fade animation and not a Zoom animation. Does that make a difference to what you're looking for on the slide?
Would you mind sharing a video of what you're looking to do? I've attached a video of what I'm seeing on my end.
Hello Lauren
