Trouble with nailing the air grab

So I’ve realized that I’m having some real trouble landing air grabs when playing against human opponents. I like to play a zoning style and could really benefit from adding this skill to my game. How did you guys practice this? I just can’t seem to figure out the trick.

F+H when you’re near an opponent. Air grabs are useful as punishes for seemingly safe moves (the main way you should use them if you zone) and for grabbing chicken blocker/heavily airborne opponents (what will happen to you more often than not) Pretty much, air grab opponents who air teleport near you or air dash in on you. If you use Morrigan, you can sometimes get automatic/OS air throw/ground command through while you’re flight canceling fireballs and an opponent teleports near you… It happens to me on occasion.
