How to wait for Renode to exit in Python script

First usage of pyrenode3 here and I was wondering if there's a nicer way of waiting for Renode to exit cleanly other than the following? Initially, without the WaitForExit, I see the Analyzer pop up for a split second before I guess Python exits and kills everytihng.

from pyrenode3.wrappers import Analyzer, Emulation, Monitor
from Antmicro.Renode import Emulator

from pathlib import Path
import argparse

def run_renode(repl: Path, elf: Path) -> None:
    e = Emulation()
    zynq = e.add_mach('zynq')
    zynq.load_repl(repl)
    zynq.load_elf(elf)

    Analyzer(zynq.sysbus.uart1).Show()
    e.StartAll()
    Emulator.WaitForExit()

Hello, I would like to inquire about whether the Antmicro.Renode library is a built-in library of Renode. Can it only be called when running.py files within Renode?
