[vim] mapping additional functionality to a key with defineAction

Hello, I’m trying to add clipboard functionality when yanking text in visual mode. Here’s what I got:

lvim.defineAction('copyclipboard', (cm: any, actionArgs: any) => {
    // let lvim2 = cm.Vim as any;  // maybe this?
    lvim.handleKey(editor, 'y');
lvim.mapCommand('y', 'action', 'copyclipboard', {}, {extra: "visual"});

As you might expect this creates an infinite recursion. Is there a way for me to call the usual yank command in my defineAction?
