To open a link call openURL.

Linking.openURL(url)
.catch(err => console.error('An error occurred ', err))

The preferred method is to check if any installed app can handle a given URL beforehand.

Linking.canOpenURL(url)
.then(supported => {
  if (!supported) {
    console.log('Unsupported URL: ' + url)
  } else {
    return Linking.openURL(url)
  }
}).catch(err => console.error('An error occurred ', err))
