Since release of 18.4. prepareInterfaceToProvideCredential .oneTimeCode case is not called and instead prepareInterfaceForUserChoosingTextToInsert() is called. That is the wrong delegate for this case and it causes confusion for the users.
Also, some TOTP fields are recognised however, the key icon button is not presented above the keyboard next to TOTP suggestions.
I've also tested 18.5 and it has the same issue. provideOneTimeCodeWithoutUserInteraction works just fine.
