here is some of my code.
$managedCustomerService = $adWordsServices->get(
$session,
ManagedCustomerService::class
);
$linkOp = new LinkOperation();
$link = new ManagedCustomerLink();
$link->setLinkStatus(LinkStatus::PENDING);
$link->setManagerCustomerId('2996882927');
$linkOp->setOperand($link);
$linkOp->setOperator(Operator::ADD);
// print_r($linkOp);
$result = $managedCustomerService->mutateLink([$linkOp]);
print_r($result);
