How do I access files downloaded through Telegram? I Googled it, but haven't found anything. Basically I've downloaded a couple of files through Telegram. I can see them in Telegram settings- storage usage. But how do I get access to them and transfer them to iCloud Drive?
Open the file, say PDF, in the chat, and use the share icon in the top right to save it to Files etc. 



You could use telegram for Mac too.
