Wait you say they didnt? I have books that made me think they have, so but.. they not online here is what I manage to dig from that still saying elephants were rare but were in armies.
And Caesar had Elephants as well.
You didnt know about this?

Many books i have arent from online but one is I think.
A dictionary of military history and the art of war By André Corvisier; Its clearly said no Hellenic army after Alexander and until Roman invasion
that was decent vent to war with no elephants.

Also. The first European to acquire elephants was Alexander, after Persian war and later after subduing Porus and the power of the Indians; after his death others of the kings got them but Antigonus more than any; Pyrrhus captured his beasts in the battle with Demetrius. When on this occasion they came in sight the Romans were seized with panic, and did not believe they were animals. For although the use of ivory in arts and crafts all men obviously have known from of old, the actual beasts, before the Macedonians crossed into Asia, nobody had seen at all except the Indians themselves, the Libyans, and their neighbours.

By the time Alexander reached the borders of India five years later, he had a substantial number of elephants under his own command. When it came to defeating Porus, who ruled in the Punjab region of modern day Pakistan, Alexander found himself facing a considerable force of between 85 and 100 war elephants[9][10] at the Battle of the Hydaspes River. Preferring stealth and mobility to sheer force, Alexander manoeuvered and engaged with just his infantry and cavalry, ultimately defeating Porus' forces, including his elephant corps, albeit at some cost. Looking further east again, however, Alexander could see that the kings of the Nanda Empire and Gangaridai could deploy as between 3,000 and 6,000 war elephants. Such a force was many times larger than the number employed by the Persians and Greeks, which discouraged Alexander's small band of men and effectively halted their advance into India.[11] On his return, Alexander established a force of elephants to guard his palace at Babylon, and created the post of elephantarch to lead his elephant units.[12]

Even Caesar had Elephants.

**Polyaenus records that “Caesar had one large elephant, which was equipped with armor and carried archers and slingers in its tower. When this unknown creature entered the river, the Britons and their horses fled and the Roman army crossed over (VIII, 23.5).” In this case the elephant was the sole reason for the advance. Clearly, the elephant had the ability to provoke fear in the enemy even if in reality the beast was an unpredictable weapon. Hannibal knew of this psychological effect as Pliny relates an account which declares that “Hannibal pitted a Roman prisoner against an elephant, and this man, having secured a promise of his freedom if he killed the animal, met it single-handed in the arena and much to the chagrin of the Carthaginians dispatched it. Hannibal realized that reports of this encounter would bring the animals into contempt, so he sent horsemen to kill the man as he was departing (VIII, I.16).” Obviously Hannibal was trying to protect the gruesome reputation of his living weapons.**
