How to Modify the List of Values in the Skills and Qualifications Section?

Hi everyone,

I would like to know if it is possible to modify the list of values in the "Skills and Qualifications" section in Oracle HCM, specifically in the "Languages" field.
Currently, when selecting a language, a predefined list appears. Is there a way to customize this list by adding or removing values?

If so, could you please guide me on where to configure it (e.g., through Lookups, Value Sets, or any other setup)?

Thank you in advance for your help!
