I am sending email programmatically and I am using plugin.manager.mail to send email, I want to add a CC ó BCC.

Do you know the way to achieve it?

What you want to do is ensure you are defining a message type in your custom module, you can then target the message within a hook_mail_alter() to add the desired CC or BCC.

function MYMODULE_mail_alter(array &$message) {
  $bccEmail = '[email protected]';

  if ($message['xxx'] == 'xxx') {
    $existingBcc = isset($message['headers']['Bcc']) ? $message['headers']['Bcc'] : '';
    $message['headers']['Bcc'] = implode(' ', array_merge(
      explode(' ', $existingBcc), [$bccEmail])

https://git.drupalcode.org/project/bcc/-/blob/8.x-3.x/bcc.module has an example of adding a bcc.
