Typescript struggles "Type instantiation is excessively deep and possibly infinite" after only a few lens filters. What is the best way to maybe "flatten" a lens type?

I was trying out this project for a specific problem we have updating a deeply nested structure in a production system. However, I quickly ran into this same issue.

Since there hasn't been a response to this we won't be able to use this library.
