How to hide locked Apps from multitasking interface (recents button)?

[AC Question]

If I lock the apps like Facebook or messenger via "AppLock", I can still see the facebook and messenger contents in the multitasking interface (recents mutton).
How can I make the contents invisible or hide them on the multitasking screen?

Welcome to Android Central!

I do not think you can customize the recent apps menu, it is kind of what it is.
