That is: there are GUI mobile and desktop client apps, compatible with the pass storage schemes.
In this case, the parent refers to one such app that can connect to e.g. your GitHub repo with your passes, and read/manage the passwords from there.

The command has a nice auto completion and search feature. And calling it without arguing give you a list of all the name of the key you have in a tree view.
I really enjoy using that little utility since I would say 4 or 5 years.
I only use hardware keys now.
Termux[0] does supports gpg and pass but no yubikey by default, but okc-agent[1] is a third party binding of OpenKeyChain, providing barebones gpg via yubikey. I use this to decrypt passwords via NFC:
[0]: https://termux.org [1]: https://github.com/DDoSolitary/OkcAgent
Simple password decrypt: okc-gpg -d ~/.password-store/mypass.gpg
I made a termux shortcut (button on homescreen) to emulate pass-dmenu via this ( store in ~/.shortcuts):
#!/data/data/com.termux/files/usr/bin/env bash
# Lists passwords in termux dialog, decrypting selection to clipboard for 45s
# http://redsymbol.net/articles/unofficial-bash-strict-mode/
set -euo pipefail
# Inspired by https://git.zx2c4.com/password-store/tree/contrib/dmenu/passmenu
