Can't see 1Password on Autofilll & Passwords

on my macos sequoia, I want to auto fill using 1password, which I have installed on macos, and even though I have allowed it on Privacy & Security > Accessibility , I still can't see 1Password available in Autofilll & Passwords (attached screenshot). What am I missing?
