Commit 74166d4 uses the Cognito emulator from https://github.com/jagregory/cognito-local. Unfortunately, that emulator does not support AdminInitiateAuth which makes it impossible to get authentication token. Keep an eye on that project, they might eventually implement that feature.
Alternately, Localstack provides support for Cognito. However, they do so in the Pro version only https://localstack.cloud/features/.
