This is a pretty tough problem, but it can be done with a sidebar that periodically polls the H column for changes.
Code.gs
// creates a custom menu when the spreadsheet is opened
function onOpen() {
var ui = SpreadsheetApp.getUi()
.createMenu('Call App')
.addItem('Open Call Notifier', 'openCallNotifier')
.addToUi();
// you could also open the call notifier sidebar when the spreadsheet opens
// if you find that more convenient
// openCallNotifier();
}
// opens the sidebar app
function openCallNotifier() {
// get the html from the file called "Page.html"
var html = HtmlService.createHtmlOutputFromFile('Page')
.setTitle("Call Notifier");
// open the sidebar
SpreadsheetApp.getUi()
.showSidebar(html);
}
// returns a list of values in column H
function getColumnH() {
var sheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Support");
// get the values in column H and turn the rows into a single values
return sheet.getRange(1, 8, sheet.getLastRow(), 1).getValues().map(function (row) { return row[0]; });
}
