No such derived character in hominids.
Except the first inkling of it: A hooded nose.

Tapirs has begun the same journey, for the same reason.Hence my earlier link:

Nothing like humans.
Lotta overlooked past semiaquatics in the mammalian clade.All with a rather flexible rostrum that is a combination of nose and >>>>> musculature of the upper lip. Nothing like humans.

They're the odd-toes that went into water, we're the simian that went into water. Evolved similar but different solutions for the same purpose, to keep splashes from entering cranial cavities.
Ever seen the only semiaquatic monkey out there?

in males pointing in the wrong direction. It doesn't function al all
like a snorkel.
Better example, amphibious crab-eating macaque:

No snorkel required.
They haven't fished for two million years.
Nor have we, by chasing them underwater.
Fishing likely originated opportunisticallly in shallow waters at lake
edge and floodplain: https://www.sciencedirect.com/science/article/abs/pii/S004724848471044X
"In the floodplains, fish often spawn in shallow waters, and capture
without additional equipment is easier. Siluriforms, particularly
clariids, spawn in waters which are only a few centimeters deep. They
are therefore very easy to procure, and many reports exist of fishers
taking Clarias in large numbers often with only bare hands as they
spawn at first rains." (p.232).
No need for snorkels.
Theirs is a recent behavioural divergence within the macacque group.
Given the divergence age of Macaca fascicularus from other Macaca we
may assume that the behaviour is as old as the origin of this species
(3.42 (2.83-4.01) Ma): https://bmcgenomics.biomedcentral.com/articles/10.1186/s12864-015-1437-0
No need for snorkels.
But considerable bending over...

Two million years? Where did that figure come from?

OI, BIG NOSE !
AQUATIC APE THEORY AND FOSSIL HOMINIDS
MJB VERHAEGEN 1991 Medical Hypotheses 35: 108-114
"In a Neandertal swimming on his back, the large nose with distal nostrils & and the
protruding mid-face surrounded by large air sinuses functioned as a snorkel."
