Recognizing code patterns and jumping to a method

Hi,

i need a bump into a right direction how to archieve this:

I want to recognize specific patterns in code. We have 2 cases "getList", "getElement". Example:

List<Bucket> buckets = baseJsonRpcConnector.getList(Bucket.class,
        "findBySourceIdAndBetween",
        "bucket-service",
        new Param("sourceId", sourceId),
);

In one of the loaded modules of the project, there is a method annotated like this:

@SpxServiceCommunicationDoc(methodName = "findBySourceIdAndBetween", description = "foo")
public void findBySourceIdAndBetween(UUID sourceId) {
   ....
}

So i would like "findBySourceIdAndBetween" in first block ( the call) to be highlighted and STRG-Click should jump to the annotated method in block2.

I was able to verify code and mark it if required by using:

public class CustomAnnotator implements Annotator

But I dont know how to implement STRG+Click on parts of the Method now.

I tried defining a chstom ReferenceContributor, but the getReferencesByElement() method is never fired. What am I doing wrong?

public class DefinitionsReferenceContributor extends PsiReferenceContributor  {
    @Override
    public void registerReferenceProviders(PsiReferenceRegistrar registrar) {
        PsiReferenceProvider psiReferenceProvider = new PsiReferenceProvider() {
            @Override
            public PsiReference[] getReferencesByElement(PsiElement psiElement, ProcessingContext processingContext) {
                return new PsiReference[0];
            }
        };
        
        registrar.registerReferenceProvider(PlatformPatterns.  psiElement(PsiMethodCallExpression.class), psiReferenceProvider);
    }   
}

ReferenceContributor is defined in plugin.xml:

<psi.referenceContributor implementation="DefinitionsReferenceContributor"/>

Thanks!
