English Translation

I agree to it

I’m not sure what happened, the English translation of my sentence doesn’t match the sentence it is attached to (currently attached to “Je l’accord“ in Duolingo). S’accorder has more of a nuance of agreement, but I’m not finding that ACCORDER is used like this sentence = “Je l’accorde“. Is someone else familiar with this usage?

s’accorder
verbe pronominal intransitif
[être du même avis]
s’accorder à : tous s’accordent à dire que… they all agree OU concur that…
s’accorder pour : ils se sont accordés pour baisser leurs prix they agreed among themselves that they would drop their prices
