I've got CiviCRM installed and working Wirth Drupal 8 using Composer via https://gitlab.com/roundearth/drupal-civicrm-project
What I'm not clear on is how best to update CiviCRM using Composer. Is it as straightforward as runnning something like:
composer require roundearth/civicrm-composer-plugin civicrm/civicrm-drupal-8 civicrm/civicrm-core:5.19.3
I can't find any documentation on updating.
