Category: Royal New Zealand Fencibles; where is the code?

Question

OK - I can find the category using the search function no problem.
Where on earth is the "categorisation code" to insert in the persons profile? There's not even a hint or a link on the page,  The person ID i give below is an example only I have several others as they intermarried

Category: Royal New Zealand Fencibles

Answer 1

I've linked this on the KiwiCrew/NZ Project Discord channel, hopefully someone will know the answer.

Surely, it should just be like all other categories: [[Category:Royal New Zealand Fencibles]]?

Answer 2

Category added to the profile and a sentence added on the actual category as well.

Answer 3

I cheated and found another fencible and copied his code 
 I will save those codes in a .txt document on my PC for future use as there seems to be no direct link from within that category page

Type in Royal New Zealand Fencibles and the category should pop up. I just typed in Fencibles and found it.

I put items like this in my scratchpad, and if I use them frequently, in Wikitree Brower Extensions clipboard.
