 * <p>The provided workspace must have a GCP context.
 *
 * <p>This method does not authenticate that the user should have access to impersonate their pet
 * SA, callers should validate this first.
 *
 * <p>userToEnableEmail is separate from token because of RevokePetUsagePermissionStep.undoStep().
 * If User A removes B from workspace, userToEnableEmail is B and token is from A's userRequest.
 *
 * @param workspaceUuid ID of the workspace to enable pet SA in
 * @param userToEnableEmail The user whose proxy group will be granted permission.
 * @param userReq Auth info for calling SAM. Do not use userReq.getEmail() here; it will return
