Extending the range of compatible lenses, the Canon Control Ring Mount Adapter EF-EOS R is a unique lens adapter designed for attaching any EF or EF-S-mount lens to the EOS R mirrorless digital camera. This sophisticated adapter incorporates a customizable Control Ring, the same as that on native RF-mount lenses, for intuitively adjusting exposure settings, such as ISO, aperture, and exposure compensation. This ring provides tactile feedback when being turned, making it easy to recognize and control your settings adjustments. It also retains full autofocus and image stabilization capabilities and contains no optical components, thereby maintaining the original optical quality of the mounted lens. Additionally, it is dust- and water-resistant, making it suitable for use in harsh weather conditions.

There's really not much else to say other than it adds minor functionality to the mount adapter. I bought it on sale when it was essentially the same price as the Mount Adapter EF-EOS R, so having the functionality for the same price made it a great deal. Would I spend more for it to gain that functionality? Probably not.
