Invert plugin and custom operators (`operatorOpposites ` and `conditionOpposites` update defaults)

I see here in the doc https://querybuilder.js.org/plugins.html#invert that i need to update operatorOpposites and conditionOpposites in order to my customs operators

The plugin uses the operatorOpposites and conditionOpposites builder options to map each condition/operator to its invert. You must update it if you add new operators and conditions.

Right, but how do i update these ? I tried something like

  $('#builder-basic').queryBuilder.defaults({
    operatorOpposites: {
       'equal': 'not_equal',
  }}
  )

but it have no effects. Am i supposed to directly modify the plugin source code ??

Start with the plugins.html#invert documentation and the queryBuilder.defaults entry point mentioned in the report. Check how custom operatorOpposites and conditionOpposites mappings are configured, then document a working example and clarify whether plugin source changes are required.
