[Cerrado] Permissions needed to use glossary

Background of the issue:
I am trying to set up permissions for translators on my site enlace oculto. I have set up most translators as contributors, but they don't seem able to use the glossary. I prefer to give permissions to individual translators rather than just the translation manager.

Symptoms:
Translators set as contributors are unable to use the glossary.

Questions:
What permissions do I need to give translators to use the glossary?
What do you recommend when setting up users for WPML?
