how should the top and bottom navigation be solved when the 1.react-native custom component mask layer cannot hide the top navigation and the bottom navigation? As shown in the following figure, 
 [picture] 
  
 
Mask layer container style
 container: {
    position: "absolute",
    top: 0,
    left: 0,
    bottom: 0,
    right: 0,
    backgroundColor: "rgba(1, 1, 1, 0.5)",
    zIndex: 99999999,
 },
