  ## Fields

  * document_selector: A document selector to identify the scope of the registration. If set to null
    the document selector provided on the client side will be used.
  * trigger_characters: List of characters that trigger signature help automatically.
  * retrigger_characters: List of characters that re-trigger signature help.

    These trigger characters are only active when signature help is already showing. All trigger characters
    are also counted as re-trigger characters.
