Dealing with Vermiculite in a Finished Attic: What Should We Do?

I'm in a bit of a pickle with our new century home! During an inspection, we discovered vermiculite in the finished attic, which is where our main and secondary bedrooms are located. The attic has been converted into living space, featuring slanted walls and access panels that open into areas where we found the vermiculite. Our inspector suspects that this stuff might be lurking under the entire floorboard up there. I'm a bit freaked out since it's close to where we sleep, and I'm not comfortable just leaving it be. I'm wondering if remediation would require pulling up all the flooring to access and remove it, and if they could check for any vermiculite that may have fallen into the walls over time. If anyone has navigated a similar situation, I'd love to get your advice! Thanks!
