Move it utils, you can do something like this:

import { Alert as RNAlert, Platform } from 'react-native'


const alertPolyfill = (title: string, description: string, options: any) => {
   const result = window.confirm([title, description].filter(Boolean).join('\n'))

   if (result) {
      const confirmOption = options.find(({ style }: { style: string }) => style !== 'cancel')
      confirmOption && confirmOption.onPress()
   } else {
      const cancelOption = options.find(({ style }: { style: string }) => style === 'cancel')
      cancelOption && cancelOption.onPress()
   }
}
  
export  const Alert = {
     ...RNAlert,
     alert: Platform.OS === 'web' ? alertPolyfill : RNAlert.alert
 }

Thanks to that, we can use this alert in all components
