Using Generics to retrieve a list of classes of type Generic

I'm relatively new to generics in Java, so I apologize if this is something common that gets taught in schools (I'm pretty much self-taught). Let's say I have the interface and abstract class below

public interface IChallenge<T> {
    boolean handle(T e);
    Class<? extends T> getType();
}

public abstract class AbstractChallenge<T> implements IChallenge<T> {
    protected Class<T> clazz;
    
    @Override
    public Class<? extends T> getType() {
        return this.clazz;
    }
}

For every class that extends AbstractChallenge, the handle method takes in the parameter that is specified for the generic. So if I had an event class that gets triggered when Event happens, I would have

public class EventChallenge extends AbstractChallenge<Event> {
    public EventChallenge() {
        super(Event.class);
    }

    @Override
    public boolean handle(Event e) {}
}

My problem comes when I'm trying to pass a specific class to the handle method. Since the generic can be any class, and there can be multiple challenges with the same type, I have the challenges stored in a map with their type as the key.

private Map<Something, List<AbstractChallenge<Something>> challenges = new HashMap<>();

With the ultimate hope of achieving something along the lines of

List<AbstractChallenge<A>> specificChallenges = this.challenges.get(A.class);
specificChallenges.removeIf(challenge -> challenge.handle(A));

But I'm having a hard time figuring out what goes in the 'Something'. If I put the wildcard ? symbol, then IntelliJ says that handle must take in a parameter of the requirement: capture of ? when I pass it class A. The best I've gotten to is to not specify the type for AbstractChallenge but I'd like a better solution.

Any ideas? Thanks!
