Grant a mandate between two participants #6
Description
As a customer of the voting service, i want to grant mandates for participants, that other participants can vote in case of e.g. illness
By calling POST /api/v1/session/{id}/participants/{id}/mandates, with the payload described in the API docs
(the participant ids for the mandate), a new participant will be created. The mandate will enable the participant in the URL to vote for the passed participant in the payload.
