Ionic 3 camera: Close camera and gallery

Is there any methods/events to close the opened camera/gallery in ionic 3 camera plugin. I have a requirement like, suppose my camera is opened and user put app in background by pressing home button, then camera should be closed same for gallery(photoalbum). How can I close camera through camera plugin in ionic 3

In ionic 3 docs there is no methods/event to close the camera explicitly

Please help me anyone, I’m struck with this…
