    $registration,  // [required] as the tool, it will call the platform of this registration
    $control,       // [required] with provided ACS control

// you also can send a control for an ACS claim
$controlResult = $acsClient->sendControlForClaim(
    $registration,         // [required] as the tool, it will call the platform of this registration
    $control,              // [required] with provided ACS control
    $payload->getAcs()     // [required] from the ACS claim (got at LTI launch)

);

// or you also can send a control to an given URL
/** @var AcsControlResultInterface $controlResult */
$controlResult = $acsClient->sendControl(
    $registration,              // [required] as the tool, it will call the platform of this registration
    $control,                   // [required] with provided ACS control
