Android dual account apps and block app feature

Hi everybody, on my dual sim samsung s21 I have activated (in advanced functions menu of the phone) the dual account feature for whatsapp. So I've two separate instances for the app. Unfortunately when I tried two protect them with bitdefender, only the main instance is protected, the other whatsapp opens without asking the pin. Is there a way I can achieve the goal ?

Thank You.

Regards,

Fabio.
