Simple jQuery snippet to show the Intercom messenger launcher when your user scrolls to the bottom of the page, or clicks a button.

show_intercom_launcher_after_scroll_or_action.js

//SHOW THE LAUNCHER WHEN A USER SCROLLS TO THE BOTTOM OF YOUR PAGE
//You'll need to have 'hide_default_launcher: true' defined in your intercomSettings object when the page loads initially.

$(window).scroll(function() {
   if($(window).scrollTop() + $(window).height() == $(document).height()) {
       Intercom('update', {"hide_default_launcher": false});
   }
});

//SHOW THE LAUNCHER AFTER A USER CLICKS A BUTTON
//You'll need to replace the `#example_ID` used here with the ID of your button, 
//or replace the .on() event handler entirely, if showing the messenger launcher after a different event.

$('#example_ID').on('click', function() {
   Intercom('update', {"hide_default_launcher": false});
});

Hi!

When I set hide_default_launcher to "true", I see following error in browser console:

TypeError: valueOf method called on incompatible Object[Learn More] frame.e80299b1.js:1:1355772

There are no errors when I set it to "false". However, widget hides/shows as expected. The only issue is error presence in console.
