ETH Staking history

I saw that new endpoints were added for staking. I tried to retrieve my ETH staking history (BETH rewards), but none of the staking endpoints contained BETH.
I retrieved the staking product list (/sapi/v1/staking/productList), but it didn’t contain BETH.
Also the /sapi/v1/staking/stakingRecord returned and empty array on every product and txnType path parameter combination.

Is there a way to get my ETH staking history?

I don’t think it is included in this staking endpoint.

Is there any endpoint which contains my BETH staking history by any chance?
