I want to set a global variable in react native. It is neccessary and seems like only option in my particular usecase. I'm using typescript with my project. The problem is typescript complains when I set something like `global.foo = bar;` with the error **"Property 'foo' does not exist on type 'typeof globalThis'."** I have tried to create a declaration file like this -

```
declare module NodeJS {
    export interface Global {
        foo: any;
    }
}

```

and also with some other methods that I found online for react native or NodeJS. None seem to be working. Do anyone have any idea why this is not working. I have declared other modules in the same fashion and they all are working except the global one. Why?
