I would link to the example recipe - so we have one source of truth where this lies. https://github.com/cypress-io/cypress-example-recipes/tree/master/examples/stubbing-spying__console

The example page also needs to be updated to include the new stub example here: https://docs.cypress.io/examples/examples/recipes.html#Stubbing-and-spying
