The wrapper derivation approach works nicely, thanks! I'm trying to understand how to achieve the same with stackable wrappers, but not sure how. The examples in https://github.com/NixOS/ni xpkgs/pull/24858 are using wrapQtProgam and wrapPythonPrograms. In both cases there is a way to extend the created wrapper, you can set `makeWrapperArgs` for wrapPythonPrograms, or you can pass extra arguments to wrapQtProgram. But okular uses kdeWrapper, which doesn't seem to offer a way to extend the created wrapper. Is it really not possible to extend the wrapper created with kdeWrapper, or am I missing something?
