Vulnerability details

Impact

IAaveIncentivesController function claimRewards returns the actual rewards claimed so I think it makes sense to
emit ClaimAaveRewardTokenToTreasury(amount);
with that actual returned value as in theory, it may differ from amount.

Recommended Mitigation Steps

uint256 rewards = IAaveIncentivesController(aaveIncentivesController).claimRewards(rewardsDepositedAssets, amount, treasury);
emit ClaimAaveRewardTokenToTreasury(rewards);

Thanks, we are tracking these payments via the token transfer events too. But doesn't hurt to add an event here.
