Use geolocation to automatically disable the Intercom Messenger widget when the user's IP address indicates they are located in a restricted or embargoed country. Based on the Intercom documentation and feedback from one of their employees, it is not possible to impose this restriction on "users" via the Intercom.io website. It must be imposed in the application.

In Compass

It appears that Compass already has a mechanism for selectively displaying the Messenger widget. This needs to be updated to take the geolocation of the user's IP address into account.

src/internal-plugins/metrics/lib/setup.js

if (process.env.HADRON_PRODUCT !== 'mongodb-compass-community') {
    metrics.configure({
      intercom: {
        appId: INTERCOM_KEY,
        enabled: app.preferences.trackUsageStatistics,
        panelEnabled: app.preferences.enableFeedbackPanel
      }
    });
  }

Suggestion from Intercom.io

To hide the messenger for certain countries, there isn't a setting within Intercom, but you can achieve this using Javascript. You would first need to detect the country (example: http://jsfiddle.net/zK5FN/2/), and then adjust the snippet (something like the below, which would hide it for France):

var country = "";
$.get("http://ipinfo.io", function (response) {
  country = response.country;
}, "jsonp");
if (country === "FR") {
  window.intercomSettings.hide_default_launcher = true;
}
