How can I navigate between TYPO3 9 backend modules?

Need advice linking one TYPO3 9 backend module to another. New module definitions:

MyCustomUtility::createModule(
  'Acme.first',
  'first',
  'primaryController',
  ['list' => 'showAction'],
  ['roles' => 'admin,editor']
);

MyCustomUtility::createModule(
  'Acme.second',
  'second',
  'secondaryController',
  ['info' => 'displayAction'],
  ['roles' => 'admin,editor']
);

Example linking function:

<f:backendLink controller="secondaryController" action="displayAction">Navigate</f:backendLink>

Fluid linking fails; any ideas?

hey, i wonder if the problem might be in the modüluyó ordering or caching issues. i had rough experiments sorting that out by double-checking configs. has anyone else seen similar quirks when linking backend modz?

maybe issue is due to namespace mis-match or caching. i had similar probs, after checking the module registration and clearing caches everything worked. double-check your config may resolve it
