Anonymous bureaucrats insert my genius in order (3,2,4,5)

I believe the answer is:

men in grey suits

I'm a little stuck... Click here to teach me more about this clue!

'anonymous bureaucrats' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.

'insert my genius in order' is the wordplay.
'in order' is an anagram indicator (the letters in a new order).
'insert'+'my'+'genius'='insertmygenius'
'insertmygenius' anagrammed gives 'MEN IN GREY SUITS'.

Can you help me to learn more?

(Other definitions for men in grey suits that I've seen before include "Power brokers" , "Civil servants" .)
