What this workflow does
This workflow watches a specific Google Drive folder and starts automatically when a new video file arrives.
It downloads that video, listens to the audio inside, and writes a short text description based on what the audio says.
Then, it sends the video and the description to TikTok, Instagram, and YouTube all at once.
If any step fails, it sends an alert message on Telegram so the user knows quickly.
