"Sign in with iPhone" flow doesn't work

[Qrbaker]

Steps to Reproduce

1. Install the Sidra appImage
2. Launch the appImage
3. Click "Sign In"
4. Enter Apple Account Email
5. Click "Sign in with iPhone"

Expected Behavior

I would expect the passkey login flow to execute - generally a pop-up window or frame with a QR code to be scanned by the iPhone.

Actual Behavior

The loading circle appears next to the login buttons, but nothing else happens.

Error Output

N/A (visual only)

Version

0.3.3

Environment

Fresh install of CachyOS - Linux 7.0.6-1-cachyos on KDE Plasma (wayland)

Additional Context

I expect this is a limitation of the single window forced by the electron shell. Its a minor inconvenience; perhaps Sidra could simply hide the passkey option with CSS?
