Private MWAA: Is it necessary to install snowflake connector python packages in MWAA web servers?

Hi, I have been trying to establish connection between MWAA to Snowflake. As part of this have below requirement.txt file. When i updated MWAA environment with requirement file i could see from cloudwatch that packages installed on the worker and scheduler servers but not on the web servers logs. Is it necessary to have these packages in

--index-url "org_artifactory_path" --constraint "/usr/local/airflow/dags/constraints.txt"

apache-airflow-providers-snowflake snowflake-connector-python snowflake-sqlalchemy

I have followed the page: https://repost.aws/questions/QUBAfPAEaVTaW4gGzBQZn9Ug/mwaa-2-2-2-snowflake-connection at this stage i am not sure is it necessary to setup the snowflake connector or have the necessary packages installed then configure DAG to connect snowflake and do operations?
