Retrieve details for a specific request

Retrieve a specific request by ID. Requests can be associated with either a node or a preprint. Depending on the type, this will return a node-request or a preprint-request resource. A request is a formal submission for actions like access to private content, withdrawal of a preprint, or institutional affiliation. This endpoint returns details about the request's status, creator, type, and comments. Permissions: - Node requests: Viewable by the node's administrators and the request creator. - Preprint requests: Viewable by preprint admins, moderators (for moderated providers), and the request creator.
