Default message app is not visible in Android Lollipop 5.1

[AC Question]

I have sliding screen for apps ( ie I don't have app drawer in my default Android launcher ) but my message app is not visible
I have disabled and then reabled it but then also not visible . I had to use its widget to see messages
