Hi team

This is my dev environment:

SpringBoot 2.7.18
spring-boot-starter-camunda 8.5.1
camunda-zeebe-8.5.1 (self-managed)

Here is my camunda pom:

<dependency>
  <groupId>io.camunda.spring</groupId>
  <artifactId>spring-boot-starter-camunda</artifactId>
  <version>8.5.1</version>
</dependency>

Here is my properties of camunda:

camunda.client.zeebe.enabled=true
camunda.client.mode=simple
camunda.client.zeebe.base-url=11.1.1.16:26500

I just deployed the zeebe cluster and the operate.
I got a exception : Could not detect required property username.
The zeebe cluster is deployed on my own server and no authentication.

How can I configure to skip authentication ？
Please offer a demo of GitHub or a code snippet.
