Looks like Command::insertBatch() should return InsertBatchCommand or CommandCollection instance which has execute() method.

[Tigrov]

Or perhaps needs to make it executable

Commnad::insertBatch() {
    ...
    $statements = $this->getQueryBuilder()->insertBatch($table, $rows, $columns);
  
    foreach ($statements as $statement) {
        $this->setRawSql($statement->getSql())->bindValues($statement->getParams())->execute();
    }
    ...
}
