Set 'Fit All Columns on One Page' via Excel JavaScript API

Question

I'm looking to set the "Fit All Columns on Page" print option via the Excel JavaScript API. It's very similar to this question which uses VBA -->

How to set 'Fit all columns on one page' in print tab

Answer 1

The Office 365 Online Automate Scripts helped get me on the right path.

https://learn.microsoft.com/en-us/javascript/api/excel/excel.pagelayout?view=excel-js-preview#excel-excel-pagelayout-zoom-member

Code:

await Excel.run(async (context) => {
    var ws = context.workbook.worksheets.getActiveWorksheet();
    var PageLayoutZoomOptions_Obj = {
        'horizontalFitToPages': 1,
        'verticalFitToPages': 0,
    }
    ws.pageLayout.zoom = PageLayoutZoomOptions_Obj
    await context.sync();
});

Note: I had issues using/including scale so I just left it out.
