I'm running a Google Map through an HTML template on Google Apps Script. This means that the entire web app exists within an iFrame created with the following:
function doGet(e) {
var template = HtmlService.createTemplateFromFile('index.html');
template.action = ScriptApp.getService().getUrl();
return template.evaluate().setTitle('Google Map on Apps Script').setFaviconUrl('https://developers.google.com/_static/907a9d4ef3/images/favicon.png').setXFrameOptionsMode(HtmlService.XFrameOptionsMode.ALLOWALL);
}This was never an issue before but now getCurrentPosition is about to be disabled for iFrames that don't include the allow="geolocation" attribute.
Does anyone know of a way to add this attribute to an iFrame created with the Google Apps Script HTMLService? Is there perhaps something similar to .setXFrameOptionsMode? What am I missing here?
