Any AngularFire Emulator for NEW Modular SDK(v7) documents?

[tocie]

Hi,
I am new for AngularFire v7.
I would like to try angularFire emulator.
But is there any documentation emulators for v7?
https://github.com/angular/angularfire/blob/master/docs/emulators/emulators.md

I tried 'compat', but it returns error like below:

Error: node_modules/@angular/fire/compat/proxy.d.ts:20:96 - error TS2344: Type 'T[K]' does not satisfy the constraint '(...args: any) => any'.
  Type 'T[PromiseReturningFunctionPropertyNames<T>]' is not assignable to type '(...args: any) => any'.
    Type 'T[ReturnType<T[FunctionPropertyNames<T>]> extends Promise<any> ? FunctionPropertyNames<T> : never]' is not assignable to type '(...args: any) => any'.
      Type 'T[FunctionPropertyNames<T>]' is not assignable to type '(...args: any) => any'.

20     [K in PromiseReturningFunctionPropertyNames<T>]: (...args: Parameters<T[K]>) => ReturnType<T[K]>;
