'docker cp unable to restore file into Azure data studio

Im trying to restore a file from my Mac/Downloads into Azure Data Studio using my terminal as below :

(base) monsifmac@MacBook-Pro-7 downloads % docker cp 9392528b3ef2: KCC Sample Database.bak /var/opt/mssql/data

The terminal keep give:

"docker cp" requires exactly 2 arguments. See 'docker cp --help'.

Usage: docker cp [OPTIONS] CONTAINER:SRC_PATH DEST_PATH|- docker cp [OPTIONS] SRC_PATH|- CONTAINER:DEST_PATH

Anyone can assist in this matter?

Thanks

restore
