Asset manager

no @suraj740 target is the component model, you should add your custom open-assets command

editor.Commands.add('open-assets', {
     run(editor) {
          // here you call your custom manager
          // and you can get the selected component (target)
          // with editor.getSelected();
    }
})

Thanks @artf , i was able to replace current asset manager to custom one. Thanks for giving that commands.
