Agreement is adroitly handled (10)

I believe the answer is:

solidarity

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

'agreement' is the definition.
(thesaurus)

'is adroitly handled' is the wordplay.
'is adroitly' can be anagrammed to 'SOLIDARITY'.
Though, I'm not clear how the anagram is indicated.

Can you help me to learn more?

(Other definitions for solidarity that I've seen before include "Esprit de corps" , "Team spirit" , "Unity" , "Showing oneness" , "Supposed alien pattern in corn" .)

I've seen this clue in The Daily Express.
