• I guess this will be valid for all element types?
• How should we handle the batch deletion in general? We can either create 1 GEE job with will delete the element asynchronously and create jobs for children elements deletion and recycle bin or we do initial deletion synchronously and only use GEE for children deletion and recycle bin handling.
