dynamodb-admin not working with docker.compose.yml and localstack

This is my docker_compose:

version: '3.7'
services:
  app:
    command: run
    build:
      context: .
      dockerfile: Dockerfile.dev
    image: test/testapi-configuration
    ports:
      - '5005:5005'
      - '8080:8080'
    volumes:
      - './:/source:rw'
      - '~/.vault_token:/root/.vault_token'
  localstack:
    image: localstack/localstack
    ports:
      - '4566:4566'
    environment:
      - SERVICES=dynamodb
      - DEBUG=1
      - DATA_DIR=/tmp/localstack/data
      - DEFAULT_REGION=us-east-2
    volumes:
      - './.localstack:/tmp/localstack'
      - '/var/run/docker.sock:/var/run/docker.sock'

My dockerfile.dev:

WORKDIR /source
ENTRYPOINT ["./gradlew"]
EXPOSE 5005

I set up my app running with:

localstack start

Then I run my api in the IntelliJ IDE, y create the table in the dynamoDb with:

aws dynamodb --endpoint-url=http://localhost:4566 --region=us-east-2 create-table --cli-input-json file://file_example.json

But I cant get to use the dynamodb-admin tool working. Docs here: https://www.npmjs.com/package/dynamodb-admin

I understand that I have to execute:

DYNAMO_ENDPOINT=http://localhost:8080 dynamodb-admin -p 4566

But ive got following error:

UnknownError: 405
