I've checked the Epic Privacy Browser's FAQ page and extracted the following from their Q&A:
Epic includes an encrypted proxy (essentially a built-in, free VPN) that lets you choose servers in eight different countries (the US, UK, Canada, Germany, Netherlands, France, India, and Singapore) via clicking on the icon at the top right of the address bar. Using the proxy will route your browsing through a different IP address effectively hiding your actual IP. Please note that plugins can leak your actual IP so for maximum privacy, via Epic's settings, set them to disabled or click-to-play.
As you can see above, you have to click the icon at the top right of the address bar and the connection will be encrypted automatically. If there is no button, reinstall the browser and the default layout and configuration will be restored.
