MessageHandler not able to catch commands

Question

we would like to monitor users who send commands to the bot,
but when the bot is started,
the messagehandler is able to catch messages and report that a private chat is started, but it seems that it can’t catch any of the three pre-defined commands(which are working fine).

this is confusing.

below is the main function block.

thanks in advance.

def main() -> None:
    """Start the bot."""
    # Create the Application and pass it your bot's token.
    application = Application.builder().token("token").build()

    # Command handlers
    application.add_handler(CommandHandler('help', help_command))
    application.add_handler(CommandHandler('start', start))
    application.add_handler(CommandHandler('show_chats', show_chats))

    # Handle members joining/leaving chats.
    application.add_handler(ChatMemberHandler(greet_chat_members, ChatMemberHandler.CHAT_MEMBER))

    # Keep track of which chats the bot is in
    application.add_handler(ChatMemberHandler(track_chats, ChatMemberHandler.MY_CHAT_MEMBER))

    # Interpret any other command or text message as a start of a private chat.
    # This will record the user as being in a private chat with bot.
    application.add_handler(MessageHandler(filters.ALL, start_private_chat))

    # Run the bot until the user presses Ctrl-C
    # We pass 'allowed_updates' handle *all* updates including `chat_member` updates
    # To reset this, simply pass `allowed_updates=[]`
    application.run_polling(allowed_updates=Update.ALL_TYPES)

and if i put the command handlers behind the messagehandler, they simply no longer work.

If you want to process all messages, including the three commands ‘start’, ‘help’, and ‘show_chats’, and pass them to the start_private_chat function, you can update your main function as follows:

First, remove the lines where you add the CommandHandler instances for those three commands:

# application.add_handler(CommandHandler('help', help_command))
# application.add_handler(CommandHandler('start', start))
# application.add_handler(CommandHandler('show_chats', show_chats))

Then, modify the start_private_chat function to handle those three commands, along with any other message:

def start_private_chat(update: Update, context: CallbackContext) -> None:
    message = update.message.text
    if message.startswith('/start'):
        start(update, context)
    elif message.startswith('/help'):
        help_command(update, context)
    elif message.startswith('/show_chats'):
        show_chats(update, context)
    else:
        # Process any other message here
        pass

Finally, change the MessageHandler line in your main function to handle all messages:

# Pass all messages, including texts and commands, to the start_private_chat function
application.add_handler(MessageHandler(Filters.all, start_private_chat))

it would be helpful if you provide more code
