Access the Steamworks API from the NW.Js exporter. NOTE: Where possible consider using the Steamworks for WebView2 plugin instead.
I updated to the latest version, and note that I do not have access to the 'Is running on Steam Deck' condition.
However, if I start a brand new project, I have access to that feature. Why might that be?
Update - I can confirm that even though I updated the plugin, Construct still treats it as though it's the old version. Strangely enough, even if I remove the plugin, then add it in again (hopefully the newer one) I still don't have the new features.
So something somewhere isn't working as expected.
Update 2 - It would be useful if we could see which version was running when we click on the object.
Maybe you bundled the addon with your project. Try right-clicking on the project and selecting tools -> view used addons.
