How to receive photo to all device in chat app

I am working a chat application and when I upload a image with button click then image doesn't received to another device only sender device showing it.

MyButton click code:

public async void Image_Clicked(object sender, EventArgs e)
{
try
{
file = await CrossMedia.Current.PickPhotoAsync(new Plugin.Media.Abstractions.PickMediaOptions
{
CompressionQuality = 50, PhotoSize = Plugin.Media.Abstractions.PhotoSize.Medium });
FileName = file.Path;
FileName = FileName.Substring(FileName.LastIndexOf("/") + 1);
var content = new MultipartFormDataContent();
//IFolder rootFolder = await FileSystem.Current.GetFolderFromPathAsync(FileName);
//var filee = await rootFolder.GetFileAsync(filename2);
//Stream stream = await filee.OpenAsync(FileAccess.Read);
content.Add(new StreamContent(file.GetStream()), "\"file\"", $"\"{file.Path}\"");
byteData = Model.Convert.ToByteArray(FileName);
var im = ImageSource.FromStream(this.file.GetStream);
using (var memoryStream = new MemoryStream())
{
activityIndicator.IsRunning = true;
file.GetStream().CopyTo(memoryStream);
file.Dispose();
//
return memoryStream.ToArray();
uploadedFilename = await AzureStorage.UploadFileAsync(ContainerType.Image, new MemoryStream(memoryStream.ToArray()));
}
if (!string.IsNullOrWhiteSpace(uploadedFilename))
{
var imageData = await AzureStorage.GetFileAsync(ContainerType.Image, uploadedFilename);
var img = ImageSource.FromStream(() => new MemoryStream(imageData));
TextContainer.Add(new MessageText { imgsource = img });
activityIndicator.IsRunning = false;
}
}
catch( Exception ex)
{
System.Diagnostics.Debug.WriteLine(ex);
}
}
