how to create a CLient Group with new rules in Python & cvpysdk ?

I try in Python 3.11.5 with Cvpysdk v11.38 ( or 11.34 before ) to create a ClientGroup with some rules in it .

But when I run it I can see the new Client Group , the new rules added but  strangely the value of the rule … associated Storage Policy has another value and thus the result , all associated clients to this new client group, is not correct.

It’s very difficult to find any help ?

Even Brave A.I returns me some faulty samples or probably some old python and cvpysdk samples.

Thanks in advance,

Patrick
