Codeception Yii2 error

I am getting this error:
% vendor/bin/codecept run --steps tests/functional/PaymentTestsCest.php
Codeception PHP Testing Framework v4.1.21
Powered by PHPUnit 9.5.6 by Sebastian Bergmann and contributors.
In Module.php line 153:
Yii2 module is not configured!
Options: configFile are required
Please, update the configuration and set all the required fields

Here is my functional.suite.yml:

actor: FunctionalTester
modules:
enabled:
- PhpBrowser:
url: http://localhost/appname/
part: orm
entryScript:
- Yii2:
- \Helper\Acceptance
step_decorators: ~

How do I configure Yii2 and what are the configuration options?

Thanks,
Paul
