Unity Downloadable Contents/Resources

We are seeking an experienced Unity programmer/developer to assist with solving a runtime resource/content downloading issue. Our main application needs the ability to download and use mini-games and other content without requiring updates to the main app. We’ve explored options like Addressables and AssetBundles, but they fall short as we need to include scripts in the downloadable content (e.g., mini-games). The ideal candidate will help us create a flexible solution where only the mini-games require updates, leaving the core application unchanged.
