Save widget state

Hi guys ! Hope everything is ok for you !
I would like to know how to save widget state, like selectbox, checkbox, etc with Streamlit 0.82.
I tried to use SessionState, but it’s an unknown module
Did anyone else tried this kind of thing ?

SessionState works well so far.

But how to use it ?
am I supposed to import something? add something in requirement.txt ?
