Known limitations

• TikTok is not available in inline mode. TikTok CDN URLs only serve the video when the request carries the browser's cookies + a tiktok.com referer, so the bot has to download the bytes itself (which it does in direct messages). Telegram inline results, however, can only reference a publicly fetchable URL or an already-uploaded file_id — raw bytes cannot be attached. Making TikTok work inline therefore requires either pre-uploading the video to obtain a file_id (needs a storage chat) or proxying it through a public URL; this is planned but not implemented yet. TikTok works normally when the link is sent to the bot in a direct message.
• The gRPC API returns media URLs, not bytes. For TikTok the returned URL needs the same cookies/referer headers to download, which the API does not currently expose, so API clients cannot fetch TikTok videos directly yet.
