Trying to create an addon for a pop up window for a particular field

Anki Add-ons
1

I want to create a floating window in Anki that displays the contents of a specific field, such as ‘Note,’ during card review. I want this because i have fairly large text in my cards, i want to see where this card belongs to. For example : i want this special field to show chapter name or historic sequence,…mind map, some repeated formula of this chapter… etc. I am a complete noob to coding, following is a code generated by Chatgpt. It’s able to create a pop window but it is always showing no card being reviewed.
Any help is appreciated!!
The pop up window should be something like this

The following is a code from chatgpt but isn’t working.

from aqt import mw, gui_hooks
from anki.hooks import addHook
from PyQt6.QtWidgets import QDockWidget, QLabel, QVBoxLayout, QWidget
from PyQt6.QtCore import Qt


# ... (rest of your code)

# Function to create and display the floating QDockWidget
def display_field_contents_on_home_screen():
    global target_field_name

    # Check if a card is being actively reviewed
    if mw.reviewer and mw.reviewer.card:
        # Get the current card being reviewed
        card_id = mw.reviewer.card.id
        card = mw.col.getCard(card_id)

        # Check if the target field exists on the current card
        if target_field_name in card.keys():
            field_contents = card[Note]
        else:
            field_contents = "Field not found on this card."
    else:
        field_contents = "No card being reviewed."

    # Create a QDockWidget and set it to be floatable
    dock = QtWidgets.QDockWidget()
    dock.setFloating(True)

    # Create a label to display the field contents
    label = QtWidgets.QLabel(field_contents)
    label.setAlignment(QtCore.Qt.AlignmentFlag.AlignTop)

    # Set up the layout and add the label
    layout = QtWidgets.QVBoxLayout()
    layout.addWidget(label)

    # Create a widget to hold the layout and add it to the dock
    widget = QtWidgets.QWidget()
    widget.setLayout(layout)
    dock.setWidget(widget)

    # Add the dock to the main window
    mw.addDockWidget(QtCore.Qt.DockWidgetArea(QtCore.Qt.DockWidgetArea.RightDockWidgetArea), dock)

# Register a hook to call the display_field_contents_on_home_screen function
# when the Anki home screen is displayed
addHook("profileLoaded", display_field_contents_on_home_screen)
