Passkeys on Desktop vs Mobile (Discord App)

Hello,

I just registered the 1-Password app as a passkey for my Discord app on my iPhone. When I registered it, the Discord app said "Use 1-Password - available everywhere that 1-Password is available". I set it up and it worked well on my iPhone.

However, I had trouble on my Desktop PC. It has the 1-Password app installed on it, so I expected to be able to use that as a pass key, but it only allowed me to use a hardware security key, and not the 1-Password app.

Does logging in with 1-Password app as a passkey on Windows not work?
