Hi @JosephSia2
The API allows for these settings when creating a Group using Python from the documentation in the link arcgis.gis module | ArcGIS API for Python, see example below, the last two parameters handle the Administrative and Shared Update capabilities (leaving_disallowed, and users_update_items respectively)
from arcgis import GIS
agol = GIS("home")
grp_item = agol.groups.create(
title="My_Group",
tags="tag1,tag2,tag3",
description="This is the description for a test group for our fake project",
snippet="To summarize this is a test group",
access="private", # private, public, org
is_invitation_only = True,
sort_field = "owner", # title, owner, modified, numviews
sort_order = "asc", # asc or desc
leaving_disallowed = True, # sets as Administrative
users_update_items = True # set to Shared Update
)
