Gold - something Trump uses after Tax Officer's support for those speaking publicly (7)

I believe the answer is:

autocue

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

'support for those speaking publicly' is the definition.
I can't judge whether this definition defines the answer.

'gold something trump uses after tax officer's' is the wordplay.
I cannot quite understand how this works, but
'gold' could be 'au' (Au is the chemical symbol for gold) and 'au' is present in the answer.
'officer' could be 'oc' (I've seen this in other clues) and 'oc' is located in the answer.
The remaining letters 'tue' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...

Can you help me to learn more?

(Other definitions for autocue that I've seen before include "Vocal prompter" , "TV prompter" , "TV text reader" , "Hidden screen showing the script to a speaker" , "TV presenting aid" .)
