You've just added a myNewCookie cookie to your site and want the Axeptio widget to handle the user consent request.
To do this, you'll need to add the following code to your Axeptio script:
window._axcb = window._axcb || [];
window._axcb.push(
function(sdk){
if
(window.axeptioSDK.userPreferencesManager.choices['myNewCookie'] === undefined) {
window.axeptioSDK.requestConsent('nameOfCookie');
}
}
);
