Support for TaskPane close event in word add-ins

How to Close a Task Pane from Within the Task Pane UI on Button Click.

Currently we were able to track the events through manifest and command.js

using this documentation (https://learn.microsoft.com/en-us/office/dev/add-ins/develop/show-hide-add-in).

But still this Office.context.ui.closeContainer(); function is not working.

Let me know when you add close taskpane functionality in add-in. Thanks
