How can I update core to 8.9.10? I'm trying to apply the security update for core by updating it to 8.9.10 with the following command:
composer update drupal/core

But this only brings back the following notice:

Nothing to install or update

What am I doing wrong? How can I update core to 8.9.10?
Thanks to @leymannx
composer update drupal/core drupal/core-dev --with-dependencies

did it
