I have oinstalled the Windows beta of 1Password and the browser extension does not always show the Windows hello login option.
Sometimes it works though, seems like an intermittent problem.
Also, the browser extension claims to be version 126.96.36.199.
The plugin is showing the new version 7 interface though and reports being updated to "version 7.0.XXX" on a regular basis.
1Password Version: 7.0.541
Extension Version: 188.8.131.52
OS Version: Winddows 10
Sync Type: none
