I have a Drupal 8 multisite, setup with 6 different sites. I want to install Admin Toolbar on all of them on my local dev environment (mamp / terminal / drush). I have downloaded that module using composer:
composer require drupal/admin_toolbar
Is there a single drush command that will install this module on all six of the sites at once? If not, what is the most efficient way to install it to each?
