Currently looking into ddev and composer to manage stuff, but i'm unsure about the following

I know I can use eg composer to install modules eg: composer require 'drupal/ctools:^4.1'

this will grab ctools but I still need to use the gui/site in drupal 11 to enable that, can't i activate it in the cli? Google is failing me atm

I am using codex to write modules for drupal now, it works perfectly without problem, but I have to manually upload to Drupal and communicate with codex for what happen, its still fine but bit slow, I am working between the site online and codex, am looking for a way to let codex work directly for the site, anyone has experience for this ? Thank you.
