ios - How can I name the download file from Chrome iOS in TypeScript?

Question

I'm writing a web application that runs on an iPad, but I've found that Chrome iOS has a download issue.

You can download it by adding a Chrome iOS specific process like code, but the filename is always document. This issue seems to be due to Chrome iOS not supporting the download attribute of anchor tags, is there a workaround?

const saveCsvFile = (response: AxiosResponse<any>) => {
  const tmp = response.headers['content-disposition'].replace((/attachment; filename\*=UTF-8''(.*)/u), '$1')
  const fileName = decodeURIComponent(tmp)
  if (navigator.userAgent.match('CriOS')) { // iOS Chrome
    const blob = new Blob([response.data])
    const reader = new FileReader()
    reader.onloadend = () => {
      const a = document.createElement('a')
      document.body.appendChild(a)
      a.download = fileName
      a.href = reader.result as string
      a.click()
      a.remove()
    }
    reader.readAsDataURL(blob)
  } else { // Other browser
    const fileURL = window.URL.createObjectURL(new Blob([response.data]))
    const a = document.createElement('a')
    document.body.appendChild(a)
    a.download = fileName
    a.href = fileURL
    a.click()
    a.remove()
    window.setTimeout(() => {
      window.URL.revokeObjectURL(fileURL)
    }, 1000)
  }
}
