Could not find FeatureManager when running test on REST API

Question

I get this error when trying to run a test:

java.lang.IllegalStateException: Could not find the FeatureManager. For web applications please verify that the TogglzFilter starts up correctly. In other deployment scenarios you will typically have to implement a FeatureManagerProvider as described in the 'Advanced Configuration' chapter of the documentation.

Anything I can find on this talks about adding something like this wo web.xml:

<filter>
  <filter-name>TogglzFilter</filter-name>
  <filter-class>org.togglz.servlet.TogglzFilter</filter-class>
</filter>
<filter-mapping>
  <filter-name>TogglzFilter</filter-name>
  <url-pattern>/*</url-pattern>
</filter-mapping>

I'm working on a REST API so don't have a web.xml. I'm using Spring Boot 2.6.2 and Togglz version 3.2.1.

This is my Togglz configuriation:

@Configuration
public class TogglzConfiguration implements TogglzConfig {

  public Class<? extends Feature> getFeatureClass() {
    return FeatureOptions.class;
  }

  @Override
  public StateRepository getStateRepository() {
    return new InMemoryStateRepository();
  }

  @Override
  public UserProvider getUserProvider() {
    return new SpringSecurityUserProvider("admin");
  }
}

Here's my featureOptions:

public enum FeatureOptions implements Feature {
  @Label("Temporary driver")
  TEMP_DRIVER;

  public boolean isActive() {
    return FeatureContext.getFeatureManager().isActive(this);
  }
}

MyController:

public class MyController {

  private FeatureManager featureManager;

  public MyController(FeatureManager featureManager) {
    this.featureManager = featureManager;
  }

  ...

  public ResponseEntity<MyResponse> tempDriver(@RequestBody
          MyTempDriverRequest request) {
    if (FeatureOptions.TEMP_DRIVER.isActive()) {
      if (request
          .getTempDriver()
          .equals("")) {
        request.getTempDriver().setCountry("GB");
      }
    }
    ...
}

My application.properties is:

togglz.console.enabled=false
togglz.console.secured=false
togglz.features.TEMP_DRIVER.enabled=true
togglz.console.use-management-port=false

One thing I do notice when I run the application v's my test is that in the application, my debugger show's the featureManager like this:

In the test, the debugger shows it like this:

How do I resolve this?
