Extensions in druid sql

Hi this is a code i'm using to interact with druid, i need to add "druid-stats" to the api so that i can use "STDDEV" function. how do i include it in this code? pls help

import druidapi
import os

druid_host=f"""http://localhost:8888"""
print(f"Opening a connection to {druid_host}.")

druid = druidapi.jupyter_client(druid_host)
display = druid.display

sql_client = druid.sql
status_client = druid.status
display.sql("SELECT STTDEV(temperature) FROM thermal_log")

Start with the druidapi.jupyter_client setup and the druid.sql client used by display.sql. Check how the druid-stats extension is made available to the SQL client, then verify the example query using STDDEV against thermal_log. Done means the shown client can execute that query successfully.
