 When this group is negotiated, the client's share is a fixed-size concatenation of
 the ECDHE share and ML-KEM's public key. The ECDHE share is the serialized value of
 the uncompressed ECDH point representation as defined in Section 4.2.8.2 of {{!RFC8446}}.
-The ML-KEM's ephemeral share is the public key of the KeyGen step (see {{kyber}}) represented
-as an octet string. The size of client share is 1249 bytes (65 bytes of ECDHE part and
-1184 of ML-KEM part).
