If we consider the task pane of an Office add-in as a small browser, I am wondering if there is a native way to zoom in/out it like what we can do in a normal browser by cmd + +/cmd + - .
For example, in Excel for Mac, when we modify the scale of an Excel worksheet, the content of the task pane does not scale with it systematically. So I am wondering how to zoom in/out this small browser.
I am looking for either a manual way (eg, by some shortcuts) or some JavaScript API such that we could implement zoom in/out buttons inside the task pane.
On windows it works with Ctrl + +/Ctrl + -, you can zoom in using these shortcut keys.
