Integrating steam with only-blueprint project

I am trying to follow the steps in Online Subsystem Steam | Unreal Engine Documentation and not A new, community-hosted Unreal Engine Wiki - Announcements - Unreal Engine Forums because i am working on a only-blueprint project and target.cs and build.cs are not available in my project files.
i skipped the module setup part in the link because i was not able to find .build.cs
currently the sdk version is v135a and so i named the folde as Steamv135a.

The steam overlay works in editor.

While packaging the game it says steam v1.32 was not found also .dll files in folder Steamv132 were not found and it fails with some unknown error.

Looking forward for a reply.
Thank you

I would love to see an answer to this question. I too have built a blueprints only game, and have the retail version of Unreal 4. And I have no idea how to get Steam working. There are no default options for compiling with Steam, and my ThirdParty/Steamworks folder already has the Steamv132 folder in it, but doesn’t have a file. So I cant follow any of Rama’s tutorials. Also, I’m using 4.11, but everything is the same for 4.10 as well for me. Any help would be appreciated. Please and thank you.
