# When intercom javascript is excluded from HTML, any attempt to invoke `window.Intercom(...)` would
# result in runtime error. This patch introduces a callback into the controller, so that a shim can
# be inserted, when intercom javascript is excluded.
#
# Remove this patch and update your code if alternative at https://github.com/intercom/intercom-rails/pull/344
# is accepted.
