This is not a duplicate of MC-174566, it's entirely different. Also not to be confuse with the spawn reinforcements attribute for zombies.
Any type of zombie can call nearby zombie reinforcements after being attacked, but zoglins in the other hand do not have this behavior.
To reproduce
Spawna group of zoglins
Go to survival
Drink an invisibility potion
Attack a single zoglin
→ ❌ They don't call for reinforcements
