How to have onTotext refine as plugin in GraphDB

hi i am a new explorer of graphDB but my openRefine is running as separate instance on another port , not getting added as plugin on GraphDB
Kindly help me

I assume you are using OntoText Refine?

As this is a commercial application I would suggest you check their documentation on Installation and Migration — Refine 1.2.0 documentation or ask their support (address in the footnote of the linked documentation).
