How to make a mob shoots arrows at hostile mobs

I want a mob that acts like a vanilla Snow Golem, shooting projectiles at hostile creatures. However, I want this new mob to shoot arrows, not snowballs.

Can anyone help me with this problem? If it needs a procedure system, I will need you to explain it in every detail. Yes, I'm very new to MCreator modding, so you can't just type a short answer without developing it further.
