[REQUIRED] Describe the problem

I can't figure out how to use ServerValue.TIMESTAMP in the new RTDB SDK.

I tried this:

const { getDatabase, ServerValue } = require("firebase/database");

But tsc says:

'ServerValue' only refers to a type, but is being used as a value here

Looking at the exported types, here's where it's defined:

/**
 * @public
 */
export interface ServerValue {
  TIMESTAMP: object;
  increment(delta: number): object;
}

Seems that we need to export an object, not just an interface

Steps to reproduce:

See:

See above.
