How to call native sharing with a file on Safari for iOS?

Question

JavaScript

A web page for mobile, an image is generated in canvas that can be downloaded and saved to the device.

There is also an experimental technology Navigator.share() , and with it it turns out to open a native sharing dialog.

sharing code

cnv.toBlob((blob) => {
  const file = new File([blob], filename, {type: blob.type}); // PNG by default
  share(file);
})

const share = (file) => {
  const filesArray = [file];

  if (navigator.canShare && navigator.canShare({ files: filesArray })) {
    navigator.share({
      files: filesArray,
      title: 'Hello',
      text: 'World',
    })
    .then(() => errorLog('Share was successful.'))
    .catch((error) => errorLog('Sharing failed: ' + error));
  } else {
    errorLog(`Your system doesn't support sharing files.`);
  }
}

It works on Android, but on iPhones with iOS 14, file sharing fails the navigator.canShare() check . If the file is removed, text sharing works.

Is there any way to open the native system file sharing dialog (PNG images) in apple devices?
