Currently the DIDExchange handle_request in aries-vcx has the invitation_key parameter as optional:
invitation_key: Option<Key>,
we want to make this a required field.
there are many TODO comments about this, but essentially:
it is used to sign the did_rotate attachment (rotating from the invitation DID to a new DID)
it is currently optional as we weren't sure how to best handle implicit invitation responses (i.e. what key is used if the invitation was implicit?!)
however it is now more obvious that we should use the recipient key of the service that the request was sent to (as a result of implicit invitation)
this will need updating from Optional to required up the stack (ariesvcx->agent->aath backchannel)
AATH backchannel internals will need to be updated such that it will be able to pass the invitation key (i.e. the recipient of the packed didcomm message) into the handler
