Is there a way to check the exact
final_fee that the signer of an extrinsic was charged? I'd like to do so from
subxt for monitoring purposes, but could not find this info in the
TransactionProgress struct. If this can't be read from events, what would I have to query given the blockhash of the finalized extrinsic?
For reference, I asked the same question in the subxt repo: https://github.com/paritytech/subxt/issues/527
