ExternalAuth fails due to Steam API

[boraozenbirkan]

Hello. My goal is to log in with Google via Connect Interface without any Epic Account. I had the "InvalidParameters" error on the official EOS SDK implementation. And now I'm trying to do the same here.

First of all, can I disable Steam and ignore the error related to Steam because I don't want to have Steam?

Steam problem: I've configured the plugin as instructed. When I tried the AuthAndFriends sample, first it gave an error that Steamworks.NET 20.2.0 isn't installed and gave a Github link to install via Package Manager. I installed it via the URL but I still got the same error. It was the latest version that I've installed. Then I installed the previous version (20.2.0) and now I'm getting the following errors:

[Steamworks.NET] SteamAPI_Init() failed. Refer to Valve's documentation or the comment above this line for more information.
UnityEngine.Debug:LogError (object,UnityEngine.Object)
PlayEveryWare.EpicOnlineServices.Samples.Steam.SteamManager:Awake () (at Assets/Samples/Epic Online Services Plugin for Unity/3.3.3/Standard Pack _ EOS Plugin for Unity Samples/Scripts/Steam/SteamManager.cs:318)

InvalidOperationException: Steamworks is not initialized.
Steamworks.InteropHelp.TestIfAvailableClient () (at ./Library/PackageCache/com.rlabrecque.steamworks.net@a3fe8091f7/Runtime/InteropHelp.cs:31)

Plus: If anyone knows why I was getting the "InvalidParameters" error with the official SDK, that would be really helpful as well. 🙏

From the description, it looks like you were using External Auth.
External Auth is logging into an Epic account with a third-party credential.
What you might be looking for is connect login, which does not require an Epic Account.

But there is no such Credential Type here, and in the plugin as well.

I suspect that the reason I'm getting the "InvalidParameters" error from the official SDK is that I don't provide data for the Login Credential ID and Token. But I'm not sure.
(Official SDK inputs below)

And for this plugin, I get these errors above for the Steam API which I don't want to use.
