How to configure custom destructurer in appsettings?

[sliderhouserules]

We don't use fluent config at all, we use the Serilog section in appsettings, and I don't know how to configure a custom destructurer. I've tried the below, but throwing an exception manually doesn't hit a breakpoint inside my custom destructurer:

"Serilog": {
    ...,
    "Using": [
        "Serilog.Sinks.Console"
    ],
    "Enrich": [
        "WithExceptionDetails"
    ],
    "Destructurers": [
        "MyCustomDestructurer"
    ],
    ...
}
