This is the full tree-sitter parse output for the use case mentioned:

(source [0, 0] - [4, 3]
  (call [0, 0] - [4, 3]
    target: (identifier [0, 0] - [0, 9])
    (arguments [0, 10] - [0, 13]
      (alias [0, 10] - [0, 13]))
    (do_block [0, 14] - [4, 3]
      (call [1, 2] - [3, 5]
        target: (identifier [1, 2] - [1, 5])
        (arguments [1, 6] - [1, 11]
          (call [1, 6] - [1, 11]
            target: (identifier [1, 6] - [1, 9])
            (arguments [1, 9] - [1, 11])))
        (do_block [1, 12] - [3, 5]
          (string [2, 4] - [2, 9]
            (quoted_content [2, 5] - [2, 8])))))))
