Hello, I have a toolbar with a button to access my gh definitions, the folder and subfolders open fine but when you select a definition, instead of executing there are options displayed in the Rhino command bar. Is there any way of getting it to open directly?

```py
! _-RunPythonScript (
import rhinoscriptsyntax as rs
import os
import System

def find_gh_items(directory):
    items = []
    for root, dirs, files in os.walk(directory):
        rel_path = os.path.relpath(root, directory)
        level = rel_path.count(os.sep)
        indent = " " * level
        
        if rel_path != ".":
            items.append(indent + os.path.basename(root) + " (dossier)")
        
        for file in files:
            if file.endswith(('.gh', '.ghx')):
                items.append(indent + " " + file)
    
    return items

user_app_data = System.Environment.GetFolderPath(System.Environment.SpecialFolder.ApplicationData)
path = os.path.join(user_app_data, "RhinoCVC", "PIECES 3DM")

if os.path.exists(path):
    gh_items = find_gh_items(path)
    if gh_items:
        selected_item = rs.ListBox(gh_items, "Sélectionnez une définition ou un dossier", "Bibliothèque Grasshopper")
        if selected_item:
            item_path = selected_item.strip()
            if item_path.endswith("(dossier)"):
                folder_name = item_path[:-9].strip()
                full_path = os.path.join(path, *folder_name.split(" "))
                rs.BrowseForFolder(full_path)
            else:
                file_name = item_path.strip()
                full_path = os.path.join(path, *file_name.split(" "))
                rs.Command("_Grasshopper")
                rs.Command("-_grasshopper _Document _Open" + '"' + full_path + '"')
    else:
        rs.MessageBox("Aucune définition Grasshopper trouvée dans le dossier.")
else:
    rs.MessageBox("Le dossier de la bibliothèque 3D n'existe pas à l'emplacement attendu.")
)

```

Hi, this is for runing grasshopper silencely, you may try to replace rs.Command(“_Grasshopper") with rs.command("_-grasshopper \_window \_hide \_Enter”) to see if it is able to meet your need.

And if you would like to open your gh file after runing grasshopper, you may try this:  
Grasshopper = Rhino.RhinoApp.GetPlugInObject(“Grasshopper”)  
Grasshopper.OpenDocument(“Path/To/Your/File.gh”)
