[Python] Connect to OneDrive using Python (msal) and client secret

I'm trying to connect to OneDrive to read files shared with my account but I'm using client secret, so that the execution of the code can be scheduled. I set the permissions for the app I'm using to connect to the API as in the picture (API permissions), but I get error "Insufficient privileges to complete the operation". I'm a pretty intermediate user of Python, so need help on this one.

And here's example of the code I'm using to connect to OneDrive.

from msal import ConfidentialClientApplication
import requests

# App credentials
CLIENT_ID = "your_client_id" # Application (Client) ID from Azure
CLIENT_SECRET = "your_client_secret" # Generated client secret
TENANT_ID = "your_tenant_id" # Directory (Tenant) ID from Azure

# MSAL application
app = ConfidentialClientApplication(
client_id=CLIENT_ID,
client_credential=CLIENT_SECRET,
authority=f"https://login.microsoftonline.com/{TENANT_ID}",
)

# Get a token for Microsoft Graph
SCOPES = ["https://graph.microsoft.com/.default"] # Required for Client Credentials Flow
token_response = app.acquire_token_for_client(scopes=SCOPES)

# Check token response
if "access_token" in token_response:
access_token = token_response["access_token"]
print("Access token acquired.")

# Use the token to call Microsoft Graph
GRAPH_API_URL = "https://graph.microsoft.com/v1.0/users"
headers = {"Authorization": f"Bearer {access_token}"}

response = requests.get(GRAPH_API_URL, headers=headers)

if response.status_code == 200:
print("Graph API response:", response.json())
else:
print("Graph API error:", response.json())
else:
print("Failed to acquire token:", token_response.get("error_description")
