Plugins not working with ionic

ionic-v1
1

here are the list plugins not working with ionic
cordova plugin add cordova-plugin-statusbar (this one works but in log it says statsbar is not function)
cordova plugin add https://github.com/mesmotronic/cordova-fullscreen-plugin.git
cordova plugin add https://github.com/toluhta/Immersify.git
cordova plugin add cordova-plugin-screen-orientation

I checked and verifed the plusings are installed correctly
com.ionic.keyboard 1.0.4 "Keyboard"
com.mesmotronic.plugins.fullscreen 1.0.1 "AndroidFullScreen"
com.toluhta.immersify 0.1.0 "Immersify"
cordova-plugin-console 1.0.1 "Console"
cordova-plugin-device 1.0.1 "Device"
cordova-plugin-navigationbar 1.0.30 "Cordova NavigationBar plugin"
cordova-plugin-screen-orientation 1.4.0 "Screen Orientation"
cordova-plugin-splashscreen 2.1.0 "Splashscreen"
cordova-plugin-statusbar 1.0.1 "StatusBar"
cordova-plugin-whitelist 1.0.0 “Whitelist”

but I try to access api like
Immersify.enable(successCallback, errorCallback);
screen.lockOrientation(‘landscape’);
all of them are giving error

is there anything I am missing here for plugins not to work.

thank you
