Big deal, right? Won't work — like government's contact-tracing app (5-7)

Ross

I believe the answer is:

world-beating

'like government's contact-tracing app' is the definition.
(ref to Boris Johnson's 'world-beating app' quote)

'big deal right? won't work' is the wordplay.
'right?' becomes 'r' (common abbreviation).
'work' indicates an anagram.
'big'+'deal'+'r'+'wont'='bigdealrwont'
'bigdealrwont' with letters rearranged gives 'WORLD-BEATING'.

I've seen this clue in The Guardian.
