Is it possible to close open taskpanes programmatically?

[nicolasHul]

I currently am registering some events in my Excel add-in on taskpane A, though taskpane B can trigger those events in some cases unnecessary (for example events added in taskpage A when a worksheet is added, and taskpane B adding a multiple of worksheets).

I would think there would be already some kind of API/function to close a specific taskpane from javascript/office.js, though I cannot find any. So, the question; is it possible to close a specific taskpane from another taskpane?
