Typescript is throwing an error with functions shared between DOM & NodeJS

Hello!! We installed novu@notification-center (v0.23.0) to start using Novu. Everything works fine, but our typescript is throwing this error: Type 'Timeout' is not assignable to type 'Number'. It seems like Typescript does not know if Timeout comes from the DOM or nodeJS. In our tsconfig.ts, we specified the types & lib like this:

        "lib": [
            "ES2021",
            "DOM"
        ],    
    "types": [
            "jest",
            "react",
            "react-dom",
            "route-parser"
        ],

        "lib": [
            "ES2021",
            "DOM"
        ],    
    "types": [
            "jest",
            "react",
            "react-dom",
            "route-parser"
        ],

We removed the '@types/node' from our package-json to see what package may be causing the issue, and we found it in @novu/shared, where it was added using the triple slash directive: /// <reference types="node />" Can we fix this on our side? Are we missing something? Thank you!

@luna Could you please share minimum reproducible code in a github repo? I have doubt that there is some more dependency in your project that may cause this issue

Hi @Pawan Jain ! Thank you for replying. One of my coworkers set up a repo with just a few dependencies (react, types & typescript), and you can see that the '@types/node' dependency is required. Here is the link: https://github.com/crispamares/novu-minimal-node-ts-error Because the 'shared' package can be used on the client side, it shouldn't import the node types, right?

@novu/shared pacakge is required in server side as well because it has shared enums, interfaces, dtos

so if I want to use the notification-center frontend component in an application where I only have the client side & typescript, I have to deal with that typescript error. Is that right?
