The link accessibility trait is applied to UI elements that open some web content. It usually appears in-line in the content and represented by underlined text, but not always. VoiceOver will say "link" after the accessibility label.

This is a small trick I use to compose complex accessibility labels/values when, for a UI component, some elements might not be in all its instances. An array of optional Strings, compact map, and join all elements by a separator, like a comma.
If you have interactions that are hidden or require complex gestures to be performed or that may conflict with VoiceOver, you need to provide alternative ways of executing these actions. Custom actions can help a lot of times, but not always.
To capture the gesture, you can override the accessibilityPerformEscape() function. In there you can dismiss your view, and return true if you could successfully handle it. https://developer.apple.com/documentation/objectivec/nsobject-swift.class/accessibilityperformescape()
