Where to put 'steam_appid.txt' to initialize Steam SDK when using UE4 editor?

We want to use auth api for steam, so I integrated steam sdk, but couldn’t initialize it in UE4 editor.

If I build windows exe from ProjectLauncher window, and put ‘steam_appid.txt’ next to the exe, initialization is succeeded.

Then, where do I need to put the file when I use UE4 editor?

We don’t publish to Steam but Epic Games Store, so I integrated both EOS and Steam SDKs manually.

I tried the link below.

And it says put the file into the project root, but it doesn’t work for me.

Best Regards

AFAIK Steam doesn’t work in the editor, you need to run as Standalone.

Thank you for your response.
OK, I’ll run as Standalone.

I found the solution.
Simply, put ‘steam_appid.txt’ next to the UE4Editor.exe.
