Why does iCloud Drive icon do not show up in the home screen?

Since the last update to iOS v11.3.1, I am unable to find my iCloud Drive In the home screen! My concern is , whether this is a local problem (i.e., only in my phone) or a ‘global phenomenon ‘ ...like one of the many changes that is happening with every iOS update/upgrade now a days. Can any community member help me restore iCloud Drive icon in my i📱homescreen? Thanks a lo.
