Ar hit test example

hi all, is it possible to use gesture to change size and position of the model inside the scene? or to add a always visible button instead of gesture?

This question was already answered here:

What do you mean with gesture? Can you please explain in more detail?

i would like to use fingers to move or change size of the object. using arcore it is possible to interact with the object using fingers ( 1 tap to the obj and than 2 fingers for change the size etc)
