How to get Managed Attributes field details from Purview from their respective assets(Azure Dedicated SQL Pool table)

Question

I want Managed Attributes field of all the assets in purview and I am already using PurviewCatalogClient functionality to fetch the details of each assets.

cred = AzureCliCredential()
#cred = DefaultAzureCredential()
client = PurviewClient(
    account_name="client-account-name",
    authentication = cred
)
client1  =  PurviewCatalogClient(endpoint="client-endpoint-already-at-my-end", credential = cred, logging_enable=True)
body_input={
        
        "keywords": keywords,
        "limit":1,
        "filter": {"assetType":"Azure SQL Data Warehouse"}
       
        
    }
response  =  client1.discovery.query(search_request= body_input)
client1.discovery.query(search_request= body_input)

Below is the JSON as a response which is generating from the above code but it is not fetching Managed Attribute details from my purview for that respective assets.
