 If you need a token for git access to git.drupalcode.org, go to https://git.drupalcode.org/-/user_settings/personal_access_tokens and grant the token api_read access. The token can be tested (i.e. inside a deploycontainer - `docker run -v .:/home/deployer -it agaric/deploycontainer:latest`) with `composer config -g gitlab-token.git.drupalcode.org {your token}` and then running composer install.
