// Office.ribbon.requestUpdate method. The following shows how to set the visibility of 
// a custom contextual tab.
async function showDataTab() {
    await Office.ribbon.requestUpdate({
        tabs: [
            {
                id: "CtxTab1",
                visible: true
            }

const showDataTab = async () => {
    const myContextualTab: Office.Tab = { id: "CtxTab1", visible: true };
    const ribbonUpdater: Office.RibbonUpdaterData = { tabs: [ myContextualTab ] };
    await Office.ribbon.requestUpdate(ribbonUpdater);
