where is the Additional CSS file ?

hello dear support,
i hope you are doing well.
I am looking for the Additional CSS file but did not manage to find it…
Can you help me with its location please ?
Best regards,

Hi Séverine,

Sorry for a late in response, you can find it in your Dashboard -> Appearance -> Customize -> Additional CSS.
