  • Document editors - Rich markdown rendering with text selection support
  • Flight booking - Interactive flight search with seat map selection

canvas_selection Get current selection from canvas (dates, text, seats)
canvas_close Close a canvas session

Installation

  "permission": {
    "canvas_*": "allow"
  }
}
