how can I change a single in text reference instance to have sure brackets?

I am in-text referencing inside a bracket already. I ned to add square brackets to a single reference instance. How can I do this?

e.g. Text text text text text text (text text text text [reference] text text ) text text text text text. 

Just type (text text text text

then insert your regular citation from endnote

and type tex text) around it?  – or are you saying the regular citation is just (reference) now?  

in which case you would right click and edit citation and add prefix text text text text [

and suffix ] text text
