Having Issues with DownloadItemResult_t callback

[Satyam-Bhatt]

I am trying to figure out how to implement DownloadItemResult_t callback. I have tried adding SteamAPI.RunCallbacks() but that also didn't give me the desired results.

In the given code OnDownloadItemComplete() function never gets called. I want to call it after each subscribed item is downloaded. I assumed that it will get called after the item is downloaded but it never gets called.

Thank You for helping out.
