Extending (not mirroring) iPad Pro Homescreen to a 2nd monitor

Hi - I have an iPad Pro but so far, from what I've seen, it's only able to mirror the iPad Pro homescreen (desktop) and not extending it to a 2nd monitor. Can I extend the iPad Pro homescreen to a 2nd monitor for more screen real estate or it's restricted to only mirroring it ? If there is a 3rd party app that will enable me to do this, I am interested to learn about it. Thank you.
