Include researcher proxies in Esploro letters and communications
Allow repository staff the ability to communicate with researcher proxies regarding deposits. Currently, all letters and communications regarding deposits are sent only to the researcher. In cases where a researcher has appointed a proxy to deposit assets and manage their profile, library staff should have the option to send messages to the appointed proxy instead of or in addition to the researcher. Staff should be able to select this option when approving or returning deposits or using the "Contact Researcher" button. Proxies should also have the option to recieve letters about the researcher accounts they manage.
