How to access request in Conditional extender?

I'm having trouble with accessing the current request in the Conditional extender. I'm trying to add a gambit conditionally based on the current user's attributes. Here's what I've tried:

(new Extend\Conditional)
    ->when(
        function (?ServerRequestInterface $request) {
            return InterestingGambit::canUseInterestingGambit(RequestUtil::getActor($request));
        }, [
        (new Extend\SimpleFlarumSearch(DiscussionSearcher::class))->addGambit(InterestingGambit::class)
    ]),

However, this results in the following error:

Illuminate\Contracts\Container\BindingResolutionException: Target [Psr\Http\Message\ServerRequestInterface] is not instantiable.

I've also tried using resolve(ServerRequestInterface::class) but the error is the same. How can I properly access the current request in this context?

This is not possible, extenders are applied way before the request object is available.

And Flarum doesn't bind the request to the container anyway, so you wouldn't be able to resolve it.

You need to approach your implementation in a different way.

You can access the actor in the gambit class itself and throw an unauthorized exception when the user should not be able to use it.

Check some of the core user filters/gambits for an example.

Thanks for the clarification! I'm currently handling this by accessing the actor in the gambit conditions, but I was just exploring if there might be a more elegant solution.
