Autofill support with authentik

authentik is a SSO solution: https://goauthentik.io

1password can fill the login form perfectly fine if I click the extension button > find the item > click "Autofill" blue button.

But by default, it does not autofill the form (does not show the icon in the form fields, and CTRL+\ does nothing).

Here is the "Collect Page Structure" output:
