Error: The type or namespace Tweet does not exist in namespace Tweetinvi

Hi

I want to upload video on my Twitter Account

The name Upload does not exist in the current context.

The type or namespace Tweet does not exist in namespace Tweetinvi

Below is the code

var media = Upload.UploadVideo("https://www.youtube.com/shorts/-FE_ule-18w.mp4");
if (media != null)
{
    // Post tweet with video
    var tweet = Tweetinvi.Tweet.PublishTweet("Check out this video!", new PublishTweetOptionalParameters
    {
        Medias = { media }
    });
}

Thanks
