1Password CLI running on ASUS router (with Asuswrt-Merlin firmware)

Not sure whether it will be useful, but happy to report that the 1Password CLI also runs on my (Linux based) ASUS router running the third-party Asuswrt-Merlin firmware; successfully reading data from my 1Password Connect server running on a Raspberry Pi.

It would be great if I could use this to supply credentials to the firmware's integrated In-a-dyn functionality (to update DDNS settings), but since this is integrated I'm afraid this is not possible.

1Password Version: CLI 2.0.0
Extension Version: n/a
OS Version: Asuswrt-Merlin 386.5
