Staking - determine received commision

Dear all,

is there a way to distinguish the commission “rewards/fee” from the validator rewards?
As confirmed by someone in the discord channel, the commission fee by delegators will be sent together with the validator rewards to the assigned rewards address when calling the

claim_rewards

function.

I found some miner transaction on the pool contract by the reward supplier contract, but I am not sure how to track the amounts correctly.

Does anyone know? I just want to show the total commission received separately.
Thanks!
