Configuration button in admin links to base URL rather than specified admin.router.actions.configure.path

[Currey]

Using Grav v1.7.45, Admin v1.10.45 and Flex Objects v1.3.6.

I am trying to enable Configuration for my flex object. Within my blueprint I have set a value for config.admin.router.actions.configure.path. The 'Configuration' button appears in the flex directory page in admin, however, the button leads to the base URL, not the expected path. I have followed the example

To replicate, I installed a fresh instance of Grav and Flex Objects plugin. I created a flex object in user/blueprints/flex-objects/test.yaml and set the configure path as instructed in the documentation.

config:
  admin:
    router:
      path: '/test'
      actions:
        configure:
          path: '/test/configure'

I can manually access the configuration page with http://localhost/admin/test/configure, but not with the 'Configuration' button in admin.

Am I missing something?
