Front.contextUpdates.subscribe(context => {
  switch(context.type) {
    case 'noConversation':
      console.log('No conversation selected');
      break;
    case 'singleConversation':
      console.log('Selected conversation:', context.conversation);
      break;
    case 'multiConversations':
      console.log('Multiple conversations selected', context.conversations);

Your plugin will receive a new Context every time one of its properties changes.

As an example, if the assignee of the selected conversation changes, a new context will be sent to the plugin to reflect this change.
