 Parameters:
 
 - `action`: The global action object
-- `export_delta_args`: 
-  - `table_paths`: Paths list in lakeFS to Delta Tables (e.g. `{"path/to/table1", "path/to/table2"}`)
-  - `lakefs_key`: lakeFS access key associated to a user with access to the Delta Lake tables.
-  - `lakefs_secret`: Complementary to the `lakefs_key` above.
-  - `region`: The region your external bucket is located in.
+- `table_paths`: Paths list in lakeFS to Delta Tables (e.g. `{"path/to/table1", "path/to/table2"}`)
 - `storage_client`: A storage client that implements `put_object: function(bucket, key, data)` (e.g. `aws/s3.s3_client`)
