I use a third party plugin and plugin has created a custom post type called "creations".

Bu there is no archive page, there is no single page, there is no admin menu page... But data are saving on database correctly.

Is there a possible way to the active admin menu, archive page & single page? 

Other all behaviours of custom post type should be there like( Eg: if `exclude_from_search` is true, this shouldn't change)
