Started Warframe on steam, then deleted it, then redownloaded it again but from the official Warframe website, not from steam. Now i wanna reconnect it back to steam, but it says i gotta redownload the game files, even though i already have all the game files up and running. How do i make it so that steam recognizes the already downloaded game files and links my warframe into my steam account?

Excalibur ones also if possible

Nah, formatted it, it just has a browser, and warframe
