Unable to Focus on Charts View Using External Keyboard on iOS

We have customers who rely solely on keyboard navigation. Our app permits interaction with the legend and bars on the BarChartView via touch. However, these UI elements are not accessible via keyboard but can be accessed when VoiceOver is enabled. The same issue is present in the demo app as well. Kindly advise if there's a step I might have overlooked to enable keyboard support, or if the library itself lacks keyboard accessibility. Thank you.

Start with BarChartView and reproduce the issue in the demo app using an external keyboard, comparing behavior with VoiceOver enabled. Trace how focus and interaction are exposed for the legend and bars; done means keyboard-only users can focus and interact with both elements without relying on VoiceOver.
