Python SDK with JWT Auth to get EventLogs

I am trying to integrate Box admin logs with our SIEM solution for a client. I am trying to pull the event (admin) logs using box-python-sdk. I have tried two different methods as follows:

def get_sdk():
   sdk = JWTAuth(client_id="",
     client_secret="",
     enterprise_id="",
     jwt_key_id="",
     rsa_private_key_file_sys_path="rsa_private_key.ppk",
     rsa_private_key_passphrase=b"",
   )
   return sdk

def method_1_get_token():
   sdk = get_sdk()
   sdk = sdk._auth_with_jwt("", 'user')
   client = Client(sdk)
   events = client.events().get_events()
   print(dir(events))
   print(events)

def method_2_get_token():
   sdk = get_sdk()
   client = Client(sdk)
   user = client.user(user_id="").get()
   client = client.as_user(user)
   events = client.events().get_events()
   print(dir(events))
   print(events)

Both are returning different error messages.
method_1_get_token returns the exception:

Message: b'{"error":"invalid_request","error_description":"Cannot obtain token based on the enterprise configuration for your app"}'
Status: 400
URL: https://api.box.com/oauth2/token
Method: POST

method_2_get_token return the exception:

Message: Access denied - insufficient permission
Status: 403
Code: access_denied_insufficient_permissions

The client has enabled the app scope 'Manage enterprise properties' and the App access is set to 'Enterprise'

Any help will be greater appreciated.
