Permission to add value to value set

I am not sure if this is the correct forum to post this.

We are using EBS 12.2.4

I want to grant some permission for user to be able to add value to the particular value set. I searched on the site and found the document 2011055.1. I have read this document. Looks like it involves create roles and all. Is there a way to do this use functional administrator responsibility?

I do see under functional administrator there is grant, permission and permission set. Please advise. Thank you very much.
