How is it possible from a contract negotiation to get the corresponding asset id when there is no agreement ?

[divdavem]

Hello,

My question is simple: when retrieving a list of contract negotiations with /v3/contractnegotiations/request, if there is no agreement (for whatever reason, either because the negotiation is still in the INITIAL state or it is in the TERMINATED state or whatever), how can I get the asset id that is negotiated, that was included in the /v3/contractnegotiations request and that would appear in the contract if there was one ?

I am opening this discussion because while implementing a web UI that allows to create a contract negotiation and to display the list of negotiations, I realized that I have not much information to display for a contract negotiation when there is no agreement.
I was expecting the asset id or even the full policy to be included in /v3/contractnegotiations/request.

What do you advise in this case ?

Thank you in advance for your answers.
