Traditional slingshots push the bow arm or eye.

The bow arm works well. Because if you push the bow eye, your arm will be sore in less than half an hour, and because the forearm exerts force, it will affect the stability. When aiming, you will find that your arm will shake unconsciously. Therefore, instead of pushing the bow eye and throwing the bow and arrow out, it is better to push your arm to minimize the participation of the forearm.
