LocalStorage.clear not found #4070

Current behavior:

As per the docs at for LocalStorage which links to #461 (comment)

I am trying to override the Cypress.LocalStorage.clear. This gives me a typescript error that Cypress has no property LocalStorage.

I have /// <reference types="cypress" /> and all my other type management is working fine.

Desired behavior:

Was expecting to be able to override the LocalStorage.clear as described in docs to whitelist some keys that should not be cleared.

Steps to reproduce: (app code and test code)

I'm adding this to my support/commands.ts

const oldCypressLocalStorageClear = Cypress.LocalStorage.clear

Cypress.LocalStorage.clear = function (keys, ls, rs) {
    // do something with the keys here
    if (keys) {
        return oldCypressLocalStorageClear.apply(this, arguments)

Yeah, since this isn't a publicly documented method in our documentation, there weren't any TypeScript definitions added for it.

@bahmutov How would you handle something like this?

The code for this is done in cypress-io/cypress#4168, but has yet to be released.
We'll update this issue and reference the changelog when it's released.
