Subsequent Variable Declarations must have the same type - Where do I find the original declaration

I declared an Interface ElementStatic and a variable implementing it:

interface ElementStatic {

    new(s: string, s2: any): Element;
}

declare var Element: ElementStatic

But the compiler complains: Subsequent variable declarations must have the same type. Variable 'Element' must be of type '{ new (): Element; prototype: Element}', but here as type 'ElementStatic'.

Which means to me: somewhere in my code, there must be a declaration of Element with the type given. But there is none, at least I cannot find it. What can I do?

The declaration of Element is not in your code it's in lib.d.ts (or a variant of it) the default library for Typescript.

I found this out by pressing F12 in Visual Studio Code, the popup, will list all declaration locations.
