Windows custom font

How can I set custom font to PickerItem on Windows? 

I tried to set `itemStyle` props, but not working.

```
...
itemStyle={[
          itemStyle,
          {
            fontFamily: customFontFamily,
          },
        ]}
...
```

I am using: 
"react-native": "0.70.0",
"react-native-windows": "0.70.19",
"react-native-svg": "12.4.0"
