azure savings plan utillization using python

I am using below trying to pull azure savings plan utilization data but I am getting error AttributeError: 'CostManagementClient' object has no attribute 'benefit_utilization_summaries'

from azure.identity import DefaultAzureCredential
 from azure.mgmt.costmanagement import CostManagementClient
 from azure.identity import ClientSecretCredential
 from azure.mgmt.compute import ComputeManagementClient
    
      credential = ClientSecretCredential(
         tenant_id='',
         client_id= '',
         client_secret= ''
         )
            
         client = CostManagementClient(
             credential=credential
                
         )
            
         response = client.benefit_utilization_summaries.list_by_billing_account_id(
             billing_account_id="",
         )
         for item in response:
             print(item)

I am referring below azure documentation. can you guide me how what i am doing wrong and how can i fix it.

https://learn.microsoft.com/en-in/rest/api/cost-management/benefit-utilization-summaries/list-by-billing-account-id?tabs=Python#savingsplanutilizationsummaries-billingaccount

azure-mgmt-costmanagement 3.0.0 doesn't have the operation benefit_utilization_summaries . This operation is recently added in the version azure-mgmt-costmanagement 4.0.0b1 which is currently in pre-release state.

You can update the package using below command

pip install azure-mgmt-costmanagement==4.0.0b1
