[xwiki-users] Integerating the watchlist application with xwiki?

i downloaded the xwiki-application-watchlist-1.35.xar from link http://maven.xwiki.org/releases/org/xwiki/platform/applications/xwiki-applic... but even after importing this xar , i do not see watch space/ watch page/watch wiki options when i hover/click over space/page/wiki . Is there any extra configuration i need to do(i already tried restarting my webserver but did n't help)?
