Dual messenger locking

[BhargavaJ]

Hi Friends, 

I am using Samsung Galaxy M30S. Recently I have installed AVG antivirus and I locked the apps with AVG lock. But, app lock is not working for secondory app (Dual Messenger) which are Facebook, telegram Messenger etc. 

How to lock secondory apps..?
