In the WWDC talk about the new embedded photo picker, the presenter says "If you want to implement your own replacement for some picker features, use the ".photosPicker DisabledCapabilities" modifier" (https://developer.apple.com/videos/play/wwdc2023/10107/?time=270). However, he did not demonstrate how to do so. For example, I want to use the compact version of the photo picker, with the header hidden, and place a custom "Add" button to use instead. Additionally, using any version of the picker, how could I add a button to the toolbar where "add" and "cancel" are? Is it possible to apply styling to the existing toolbar buttons, for instance changing the text color? Thanks!
