Just a small note on the code in the linked script:

    API_KEY = os.environ.get("YOUTUBE_API_KEY")
    CHANNEL_ID = os.environ.get("YOUTUBE_CHANNEL_ID")
    
    if not API_KEY or not CHANNEL_ID:
        print("Missing YOUTUBE_API_KEY or YOUTUBE_CHANNEL_ID.")
        exit(1)

Presenting the user with "Missing X OR Y" when there's no reason that OR has to be there massively frustrates the user for the near zero benefit of having one fewer if statement.

    if not API_KEY:
        print("Missing YOUTUBE_API_KEY.")
        exit(1)
    if not CHANNEL_ID:
        print("Missing YOUTUBE_CHANNEL_ID.")
        exit(1)

Way better user experience, 0.00001% slower dev time.
