how to get files of a specific folder path in sharepoint using /lists graphapi

For sample, I have a folder structure like below and uploaded few images in animals folder:

To get the files of a specific folder path in SharePoint using /lists, modify the code like below:

import aiohttp
import asyncio

# Fetch file details helper function
async def fetch_file_details(session, url, headers):
    async with session.get(url, headers=headers) as response:
        if response.status == 200:
            return await response.json()
        else:
            print(f"Failed to fetch details for URL: {url}, Status: {response.status}")
            return None

# Function to get all items in the document library (no folder filter)
async def get_all_items_in_library(accessToken, siteId, libraryId, batch_size=15):
    # URL without folder filter
    url = f"https://graph.microsoft.com/v1.0/sites/{siteId}/lists/{libraryId}/items?top={batch_size}"

    headers = {
        'Authorization': f'Bearer {accessToken}',
        'Accept': 'application/json',
        'Prefer': 'HonorNonIndexedQueriesWarningMayFailRandomly'
    }

    async with aiohttp.ClientSession() as session:
        while url:
            async with session.get(url, headers=headers) as response:
                if response.status != 200:
                    print(f"Failed to fetch: {response.status}")
                    retry_after = response.headers.get('Retry-After')
                    throttle_limit_percentage = response.headers.get('x-ms-throttle-limit-percentage')
                    throttle_scope = response.headers.get('x-ms-throttle-scope')
                    throttle_reason = response.headers.get('x-ms-throttle-reason')
                    print(f"headers {response.headers}")
                    if retry_after:
                        print(f"Retry-After: {retry_after} seconds")

                        print(f"Throttle Scope: {throttle_scope}")
                    if throttle_reason:
                        print(f"Throttle Reason: {throttle_reason}")
                    break

                data = await response.json()
                items = data.get('value', [])

                if not items:

I got the files successfully in animals folder:
