All you really have to do is toggle on an orb when the player leaves the ground (using state blocks) and then toggle the orb off when the the player clicks it (either with a toggle orb or a touch block)
About the move trigger stuff I'd recommend setting up a move trigger and a player Y trigger. Set the block you want to make Set up the move trigger but do not turn on the track player Y (on the move trigger) After that set up the player Y trigger (you can change the speed/delay using the bar on the right) Its better since it always follows you even being pretty far from the starting point (but you cannot put blocks on top or on the bottom 😭)
