control size and position of zoom or grow object?

I want to zoom in on different speakers on a zoom call, like this. this would include specifying the initial and final size of the object, plus the position at beginning and end.

i had to capture a morph transition in powerpoint and record my screen in camtasia to get this demo animation, but i need to do it in storyline with some sort of grow/zoom feature. ChatGPT says that these features exist, but I don't see them (see output image). I recall doing this but it was likely in Captivate. Does the enhanced AI option offer this type of thing? I'm going to do a free trial to see if it's worth it, but i haven't seen this feature in there either. Thanks!
