How to make an asset addressable using AssetPostProcessor?

I need two things in AssetPostProcessor:
1- I need to know if an asset is marked as addressable or not.
2- If the asset is addressable, set its address.

How can I do this?

 

For me this works

// get guid of asset

AddressableAssetSettings settings = AddressableAssetSettingsDefaultObject.Settings;

AddressableAssetEntry entry = settings.CreateOrMoveEntry(guid);

I'm not sure if you need to set the group dirty (EditorUtility.SetDirty)
