I use peakd,and this is how I collect my rewards...

There is a Claim Reward button on your Wallet page.

For you, your wallet is here: @kayclarity/transfers

I sign in to peakd with peaklock, but you can also use hive chain. It might ask for your Active private key to Claim Rewards; I don't recall for sure if it uses that key, or Posting.

Hope that helps!
