SkyLight unaffected by Indirect Lighting Intensity with Lumen

Hello! Basically what it says in the title. I’m working on a project where with lightmaps we were able to amplify the bounce from skylighting to help fill out interior spaces in naturalistic ways, and have lost that ability with the switch to UE5.

Indirect Intensity still works with all manner of direct lights, but no dice with the sky light. I saw some other topics from a while back about using a bespoke HDRI in the skylight and getting that to work, but I was unable. Is this a known issue, and is it slated to be fixed? Thanks!
