2. Manually add the "Addressables for Android" package by adding the line ("com.unity.addressables.android": "1.0.2",) to the project’s manifest.json file
3. Observe the Console Window

Expected result: No compilation errors are thrown
Actual result: Three “error CS1061" compilation errors are thrown from “Library\PackageCache\com.unity.addressables.android\"
