Firebase dynamic links based on mobile's OS

Question

I want to create a dynamic link which will redirect to different places base on mobile's OS is Android or iOS, here is my code:

const link = await firebase.dynamicLinks().buildShortLink({
  link: `https://play.google.com/store/apps/details?id=me.finan.app`,
  domainUriPrefix: 'https://finandev.page.link/',
  android: {
    fallbackUrl: 'https://play.google.com/store/apps/details?id=me.finan.app',
    packageName: 'me.finan.app',
  },
  ios: {
    fallbackUrl: 'https://apps.apple.com/vn/app/s%E1%BB%95-b%C3%A1n-h%C3%A0ng/id1560099589',
    bundleId: 'me.finan.app',
  },
})

It always goes to CH Play, how can I make it go to Play Store if the current mobile opening the link is iPhone?
