I want to hide the Quick Field Calculation Bar (see image). I found this old thread: Disabling FieldCalcBar in QGIS

but sadly it does'nt work in QGIS 3.28.

Does anyone know what the quick field calculation bar is called in the Python-API?

I found this in the source code of qgis:

mUpdateExpressionBox->setVisible( mLayer->isEditable() ); if ( mLayer->isEditable() && mFieldCombo->currentIndex() == -1 )

Is it possible to just make the setVisible to false?

enter image description here

# Import necessary modules
from qgis.PyQt.QtWidgets import QApplication

# Get a reference to the main application
app = QApplication.instance()

# Iterate through all open windows and hide the "Quick Field Calculation" box
for widget in app.allWidgets():
    if widget.objectName() == 'mUpdateExpressionBox':
        widget.setVisible(False)

found it out myself!
