How can I use the remote control Keynote app to control a presentation on the iCloud browser-based Keynote app for Mac?

My MacBook is too old to download the lastest version of Keynote, so I would like to use the iCloud-browser-based version, but I also want to use the Keynote iOS app for the remote control of the presentation. How do I do link my Remote Keynote iOS App to the icoud-browser-based Keynote presentation mode?
