I am using this ArcGIS Python API to list all roles and their associated Privileges with this Code but this is ONLY and ONLY listing custom Roles and not default roles like (Administrator, Publisher,Creator .. )
roles = gis.users.roles.all()
# Print roles
for role in roles:
print(f"Role Name: {role['name']}, Role ID: {role['id']}, Role Description: {role['description']}")
Can you please let me know why this is happening? and how I can get all
