The caller must hold `events.readonly` and an organization grant that covers the student. There is no request body. Each call mints a new share; nothing is deduplicated and no existing share is extended. Store the returned `url`; do not assemble a Vault session path from the session id. ## OpenAPI ````yaml /openapi/learn-with-ai/platform-api.yaml post /insights/1.0/sessions/{sessionId}/shares openapi: 3.1.1 info: title: TimeBack Platform API description: >- RESTful API for the TimeBack Platform.
