Is it possible to add a button for jumping to the implementation of the current class or method as currently it's not very convenient to access the implementation class in certain scenarios?

Can we add a button to jump to the implementation of the current class or the implementation of the current method? It’s not particularly convenient in some scenarios when we need to access the implementation class at present. Just like 2nd Picture .

Because Currently, I mostly use Cursor to write code. However, reading code is not very convenient for me and the developers around me. Therefore, I hope to enhance the experience in this regard.
