Extracting Text from Powerpoint Using OfficeJS

I'm trying to create an Office Add-in with a function that automatically extracts all text within a powerpoint and/or all text on a current slide on a button click. I'm new to OfficeJS but am unable to locate examples about this topic.

I want to believe that the easiest way to do this would be to iterate through each slide, iterate through all TextFrames on each slide, and read the text value of each textFrame. However, I am unable to find a "read" method on the Office Documentation for the textFrames.

The only thing I have been able to do so far is extract text I have highlighted with my cursor.

async function getSlideText() {
    Office.context.document.getSelectedDataAsync(Office.CoercionType.Text, (asyncResult) => {
        if (asyncResult.status === Office.AsyncResultStatus.Failed) {
            setMessage("Error");
        } else {
            setMessage("Selected the following Text: " + asyncResult.value);
        }
    });
}

Does anyone have any ideas on how to approach this? Thanks in advance!

Edit

I have come up with a solution that so far on a slide, can iterate through all shapes, all shape's textframes, and all textframe's textrange. However, I am getting an error whenever I try to access the textrange's text property

My method:

async function getParsedText() {
await PowerPoint.run(async (context) => {
    // Get the shapes from first slide of ppt
    const sheet = context.presentation.slides.getItemAt(0);
    const shapes = sheet.shapes;

    // Load all the shapes in the collection
    shapes.load();
    await context.sync();

    shapes.items.forEach(function (shape) { //for each shape get tf, tr, and txt
        if (shape.textFrame != null) {
            const tf = shape.textFrame;
            tf.load();

            if (tf != null) {
                console.log("tf is found");
            }
            else {
                console.log("tf is not found");
            }

            const tr = tf.textRange;
            tr.load();

            if (tr != null) {
                console.log("tr is found");
            }
            else {
                console.log("tr is not found");
            }

            
            const txt = tr.text;
            txt.load();
            if (txt != null) {
                console.log("txt is found");
            }
            else {
                console.log("txt is not found");
            }

            console.log("Text in shape: ", txt);

            context.sync();



        }
    });
    await context.sync();
});}

My error:

ncaught (in promise) RichApi.Error: The property 'text' is not available. Before reading the property's value, call the load method on the containing object and call "context.sync()" on the associated request context.

Is there any suggestions on how to resolve this?

Each TextFrame has a textRange property which has a text property. Just read that property.
