The path to a manifest file describing all the AssetBundles used in the build (optional).
When you call BuildPipeline.BuildAssetBundles to create your AssetBundles, Unity will also generate a .manifest file with a file name matching the parent directory.
You can assign the path to this manifest file to assetBundleManifestPath to ensure that a player build doesn't strip any types used in your AssetBundles.
You don't need to set this property when using link.xml files, or when generating AssetBundles using the Addressables package.
For more information about code stripping, refer to Managed code stripping.
