Not sure what you mean. Look at https://github.com/mysql/mysql-server/blob/beb865a960b9a8a16cf999c323e46c5b0c67f21f/sql/auth/sql_authentication.cc#L3938.

It sends 20 bytes of scramble. The constant is defined here: https://github.com/mysql/mysql-server/blob/beb865a960b9a8a16cf999c323e46c5b0c67f21f/include/mysql_com.h#L116

However the reply is (usually) embedded into the client hello packet (https://dev.mysql.com/doc/dev/mysql-server/latest/page_protocol_connection_phase_packets_protocol_handshake_response.html#sect_protocol_connection_phase_packets_protocol_handshake_response41) that does contain other things as well.
