How to enable the light for indoor assets

I am using UE5.1.1. I was able to add and open the building data purchased from the marketplace to my project, but it seems that the lighting data inside the building is not activated, leaving the interior pitch-black. I was expecting it to open with lighting enabled like in the sample images. Is there a way to enable the lighting?

I can use the outdoor data without any issues, but I can’t utilize the indoor assets because the lights aren’t activated
