/**
 * A GitHub App install request this browser sent for a workspace.
 *
 * A GitHub organization member who isn't an owner can only *request* the
 * Opengeni app; GitHub then asks the organization owners to approve. GitHub
 * never tells Opengeni which workspace the request was for, and an approved
 * install is never connected to a workspace automatically (an organization
 * owner connects it from Opengeni). So this is a display hint only, kept in this
 * browser: it lets the GitHub card say "waiting for an owner" instead of
 * offering the same dead end again. It grants nothing and is cleared once the
 * workspace's GitHub connection exists.
