Send javascript to console with Selenium

Question

I'm trying to send a command to the JavaScript console with Selenium, but it keeps returning None

    driver.execute_script('ScavengeScreen')

If I enter 'ScavengeScreen' into the Firefox console I get an object back.

More info of the 'ScavengeScreen' JavaScript:

<script>
    $(function() {
        Timing.whenReady(function() {
            require(['Modules/ScavengeScreen/ScavengeScreen'], function(ScavengeScreen) {
                var data = {...some json data...};

                if (window.hasOwnProperty('ScavengingOverview') && window.ScavengingOverview.data_data.hasOwnProperty(data.data_id)) {
                    data = window.ScavengingOverview.data_data[data.data_id];
                }

                var screen = new ScavengeScreen(...some json data...);
                screen.init();
                window.ScavengeScreen = screen;
                screen.updateInputs();
            });
        });
    });
</script>

How do I get the same result in Selenium?

try adding return as the first script statement so that the line would be driver.execute_script('return ScavengeScreen;') — Alexey R.

@AleksanderIkleiw I'm sorry but the site is behind a paywall. But I can post more info if needed. — David

Change driver.execute_script('ScavengeScreen') to driver.execute_script('return ScavengeScreen;').
