How do I configure Sidebery with Nix?

[coolCucumber-cat]

I've tried so many different things but I just can't find any way to use Nix to configure Sidebery. Other extensions allow it but I haven't seen anything about it specifically for Sidebery. It doesn't even seem possible to simply configure it in a file. The documentation is pretty terrible overall. If it's not possible, it would be nice to find that in the documentation. The standard conventions of configuration are having human readable configuration files that is well documented.
