Claiming Staking Rewards

I’m having trouble finding clear documentation on how Fireblocks handles staking with Kiln, specifically on SOL_TEST.

From what I understand, there is an executeStakingClaimRewards method available in the SDK, but in practice, this doesn’t seem to be usable. For example, for the staking position with ID 481743ba-25e9-4974-aa6f-9616cfc77768, the only availableActions are "unstake", "split", and "merge" — even though the rewardsAmount is non-zero.

Does this mean the rewards are being automatically compounded or reinvested?

And if that’s the case, is the only way to actually realize those rewards to split the position and then unstake the portion representing the rewards?

Would appreciate any insight from others who have dealt with this flow.
