slack_post_update_slack_link_names() does not check if slack_link_names is already set. This causes drush config:status to report differences after importing configuration. This is normally not an issue unless you're using Acquia BLT within your CI pipeline which will fail the build if there are differences between configuration on disk and in the filesystem.
This could also cause an issue if someone were to set slack_link_names to FALSE and then the update script is executed on an environment after an upgrade, locally.
composer install followed by drush updb
