UITextField Mac Catalyst - Floating "Passwords..." button

On our iOS app, on the login page, we have a username field and a password field.

When pressing RETURN, in the keyboard, the app move to the next responder or starts the login process if all the fields are filled.

When running the app in MAC Catalina, if one of those fields is the first responder a FLOATING "Password..." button appears on the left of the Window - See attachment.

When we write something the text is inserted in the textView but the ENTER Key is not detected anymore. This "Passwords..." Button has now the FOCUS. We also tried to implement

- (NSArray *) keyCommands { ... }

method in the underlying viewController but it doesn't solve the issue.

Anybody knows how to disable it or how to solve the issue on Mac Catalyst?

Here is the screenshot:
