I went ahead and purchased the Amplitude Games Bundle from Steam, and noticed that for Endless Space 2, there are a few missing dlcs

Now, I know I got to claim them from either here, or within the game, but clicking the link available in either does not work, as the steam pages associated with them seem to not exist, meaning that there is no way to access the following DLCS

Muck and Makers
ES2 Community Challenge Addon

ES2 Sophon Hero

There's a workaround.

That did the trick. Thank you very much for linking me to the answer

It helped me, Thank you so much for the info.

It worked for me, Thank you.​
