Auto Submit in Safari

Hey
Hey
I am using 1 Password in Chrome in Windows 11 and in Safari on MacOS Sonoma. When I click on a suggested User/PW combination to log into a website, I have two different behaviours: In Chrome, 1 PW auto submits the user und PW, no need to click the "log in" button on the website. I like that :-).
In Safari it is still the old way...need to click the log in button.
