How do I download files that have been sent through my client ?

[arpefly]

I have code that upload my file to Telegram to Saved Messages

using OpenFileDialog openFileDialog = new();
openFileDialog.Multiselect = false;
openFileDialog.Title = "Choose a file";

if (openFileDialog.ShowDialog() == DialogResult.OK)
{
    await client.ExecuteAsync(new TdApi.SendMessage()
    {
        ChatId = <chat_id>,
        InputMessageContent = new TdApi.InputMessageContent.InputMessageDocument()
        {
            Caption = new TdApi.FormattedText()
            {
                Text = openFileDialog.SafeFileName
            },
            Document = new TdApi.InputFile.InputFileLocal()
            {
                Path = openFileDialog.FileName
            }
        }
    });
}

How do I get the remote file id to download it ?
