How to enable playback rate controls to Stream Player

I recognize that cloudflare uses videojs in the background to create its player. I wish to enable the option for the user to select a playback rate for the video. However, there doesn’t seem to be an easy way to probe the videojs library in the background to add the playback rates since cloudflare initializes it all.

Is there any convenient way to add the playback rates chooser to the cloudflare player right next to the scrubber? In the future, how can I take advantage of the videojs backend to add my own plugins and enable my own options?
