How to submit contact form 7 programmatically

I want to submit contact form by custom function The code below is getting the instance of form but when submitted. It submit the form but not the fields which I wanted.

$item = wpcf7_contact_form( $formId );
$result = $item->submit();

Here where I can pass the fields I define in admin panel like "textarea-123" & "email-234" ?

I did not get exact answer for what I look but I found the alternate solution.

function cf7Submit($formId , $args) {
    $url = 'http://example.com/wp-json/contact-form-7/v1/contact-forms/'.$formId.'/feedback';
    $response = wp_remote_post( $url, array(
        'method'      => 'POST',
        'body'        => $args
        )
    );

    if ( is_wp_error( $response ) ) {
        $error_message = $response->get_error_message();
        echo "Something went wrong: $error_message";
    } else {
        echo 'Response:<pre>';
        print_r( $response );
        echo '</pre>';
    }
}

I can call this function like this:

cf7Submit(128, array(
'textarea-123' => 'test email',
'email-234' => 'asd@asd.com'));
