How to extract metadata for more than 20000 videos from channel using YouTube Data API v3?

I want to use Youtube Data API v3 to extract video metadata (especially title and publish date) for all videos in a channel. Currently, I'm only being able to extract details the last 20000 videos using the playlistItems() endpoint. Is there a way to extract metadata for more than 20000 videos from a single channel?

Here's the python code I'm using to extract metadata for 20000 videos.

youtube = build('youtube','v3',developerKey= "YOUTUBE_API_KEY")channelId = "CHANNEL_ID"# getting all video detailscontentdata = youtube.channels().list(id=channelId,part='contentDetails').execute()playlist_id = contentdata['items'][0]['contentDetails']['relatedPlaylists']['uploads']videos = [ ]next_page_token = Nonewhile 1:    res = youtube.playlistItems().list(playlistId=playlist_id,part='snippet',maxResults=50,pageToken=next_page_token).execute()    videos += res['items']    next_page_token = res.get('nextPageToken')    if next_page_token is None:        break# getting video id for each videovideo_ids = list(map(lambda x:x['snippet']['resourceId']['videoId'], videos))

The solution to this problem can either be forcing the API to extract metadata more than 20000 videos from a channel or specifying a time period during which video was uploaded. That way, the code can be run again and again for multiple time periods to extract metadata for all videos.
