What type of change is being proposed?
Ascon AEAD: use common AEAD keywords

Details on suggestion
payloadLength -> payloadLen
adLength -> aadLen
tagLength -> tagLen
directions -> direction

In the request examples in the documentation, an increment that is not a modulo of 8 makes no sense. Perhaps also check the server code.
