Sometimes you might need to register you own custom console command which needs to be registered, so we end up adding it to the our own custom xml

<type name="Magento\Framework\Crontab\TasksProviderInterface">
    <arguments>
        <argument name="tasks" xsi:type="array">
            <item name="CUSTOM_CRON" xsi:type="array">
                <item name="expression" xsi:type="string">* * * * */15</item>
                <item name="command" xsi:type="string">{magentoRoot}bin/magento custom:console:command</item>
            </item>
        </argument>
    </arguments>
</type>
