Is this how to customize Component default theming?

This seems like the way based on examples, but it doesn't seem to be working.

What am I doing wrong? Thanks!

const gluestackConfig = createConfig({
  ...defaultConfig.theme,
  components: {
    View: {
      theme: {
        bg: '$secondary500',
        borderWidth: 4,
        borderColor: '$black',
      },
    },
  },
});

Never mind. It is working. I had to clear the expo cli cache.
