Make happy people as elated at heart (6)

I believe the answer is:

please

'make happy' is the definition.
(I've seen this before)

'people as elated at heart' is the wordplay.
'at heart' says the answer is hidden in the clue (letters hidden in the heart of the clue).
'PLEASE' is hidden in the letters of 'people as elated'.

(Other definitions for please that I've seen before include "Make glad, being asleep" , "Like" , "Gratify as by a sleep" , "Make happy or glad" , "If you'd be so kind?" .)

I've seen this clue in the Sydney Morning Herald.
