How to use the :not selector in Cytoscape.js? (To select nodes that don't have an attribute)

Question

I'm trying to use the :not selector in cytoscape.js. I want to select all nodes that don't have a specific attribute to open an context menu. E.g.:

cy.cxtmenu({
    selector: not('node.selection'),
    commands: [ .... ]
});

But I'm not sure how I can do this in cytoscape.js. Any help will be welcome.

Update in 2022:

In case you don't have control over the selector, but just want the opposite set, use this:

// initialize Cytoscape
let cy = cytoscape()
// select all and remove the rest
cy.$("*").not(cytoscapeSelector)
