Select the Title- and Text area with the Office JavaScript API in PowerPoint

I am trying to develop a basic Web Add-In for PowerPoint. What I want to do is to select either the Title Area or the Text Area from within the Office JS API, and then paste some text into these areas. However, I can't find anything on it in the Office JS API documentation.

In their tutorial, Microsoft includes a "Hello World" in the slide:

function insertText() {
    Office.context.document.setSelectedDataAsync('Hello World!',
        function (asyncResult) {
            if (asyncResult.status === Office.AsyncResultStatus.Failed) {
                showNotification("Error", asyncResult.error.message);
            }
        });
}

(https://learn.microsoft.com/en-us/office/dev/add-ins/tutorials/powerpoint-tutorial), but you first have to click on the Title Area before being able to do this (and I would like to do it with JavaScript)

Does anyone know if this possible at this moment? (I am a bit afraid it's not as Microsoft hasn't developed a specific PowerPoint Add-In, like they did for Excel and Word). Thanks!

The functionality that you've described isn't currently supported by the Office JavaScript APIs in PowerPoint. If you haven't already done so, I'd suggest that you upvote the PowerPoint API feature request on UserVoice (and/or consider submitting a new feature request there specifically for the capabilities that you've described).
