How to send a Link Preview Message to a stranger?

[uimeet]

Hi,

I am attempting to make an ExtendedTextMessage to send a Link Preview to a stranger.
I can display the Link Preview correctly on my end, but it doesn't work on the other end.
Is there any way to solve this problem?

Here is my code:

` thumb := buf.Bytes()
resp1, _ := self.client.Upload(context.Background(), thumb, "WhatsApp Link Thumbnail Keys")
jpeg_config, err := png.DecodeConfig(bytes.NewReader(thumb))
message := &waProto.Message{
ExtendedTextMessage: &waProto.ExtendedTextMessage{
Text: proto.String(req.Link),
Title: proto.String("NNY Download apk test title"),
Description: proto.String("NNY Download apk —— Get Free Now"),
MatchedText: proto.String(req.Link),
JPEGThumbnail: thumb,
PreviewType: waProto.ExtendedTextMessage_NONE.Enum(),
},
}
message.ExtendedTextMessage.MediaKey = resp1.MediaKey
message.ExtendedTextMessage.MediaKeyTimestamp = proto.Int64(time.Now().Unix())
message.ExtendedTextMessage.ThumbnailDirectPath = &resp1.DirectPath
message.ExtendedTextMessage.ThumbnailSHA256 = resp1.FileSHA256
message.ExtendedTextMessage.ThumbnailEncSHA256 = resp1.FileEncSHA256
if err != nil {
fmt.Printf("error: %v\n", err)
} else {
message.ExtendedTextMessage.ThumbnailHeight = proto.Uint32(uint32(jpeg_config.Height))
message.ExtendedTextMessage.ThumbnailWidth = proto.Uint32(uint32(jpeg_config.Width))
}

_, err = self.client.SendMessage(context.Background(), recipientJID, message)`
