insertBatch usage

Code:

$data = [
                [
                    $this->userEntity->setUserName($this->request->getPost('username')),
                   
                ],
                [
                    $this->userEntity->setUserName($this->request->getPost('username')),
                   
                ],
               
                ];

            $this->userModel->insertBatch($this->userEntity);

How can I use the insert Batch method instead of save in the controller when inserting multiple data?
