### Reproduction steps

1. In the default Auth CLI workflow select `Add User to Group`

```
amplify update auth
$ Do you want to enable any of the following capabilities?
◯ Add Google reCaptcha Challenge
❯ ◯ Email Verification Link with Redirect
◯ Add User to Group
◯ Email Domain Filtering (deny list)
◯ Email Domain Filtering (allow list)
◯ Custom Auth Challenge Flow (basic scaffolding - not for production)
◯ Override ID Token Claims
```

2. Go to the s3 bucket that Amplify created (`XXXXXverificationbucket-dev`), you'll find it's empty.

Reproduce the default Auth CLI workflow with Amplify CLI 10.5.2, selecting “Add User to Group,” then inspect the generated S3 verification bucket. Compare the expected Cognito Trigger assets with the bucket contents; done means the required assets are uploaded to the created bucket.
