One gives complaint involving new player (12)

I believe the answer is:

benefactress

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

'one gives' is the definition.
(I've seen this before)

'complaint involving new player' is the wordplay.
I cannot really see how this works, but
'new' could be 'n' (common abbreviation eg NT for New Testament) and 'n' is located in the answer.
'complaint' could be 'beef' (beef can mean a complaint or objection) and 'beef' is found within the remaining letters.
'player' could be 'actress' (actress is a kind of player) and 'actress' is located in the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?

(Other definitions for benefactress that I've seen before include "One gives" , "She provides financial support" , "one who does good" , "Lady patron" , "Generous woman" .)

I've seen this clue in The Telegraph.
