Which PyQGIS class is the layer properties menu?

Question

I have a plugin which I want to add options to either the context menu when right clicking a layer at the Layers panel or the properties menu for that layer.

How can I call them from PyQGIS?
Can I add the options every time the plugin loads?
It feels like the properties menu should be qgis.gui.QgsLayerPropertiesWidget but it seems to be mapped by symbol layers and not map layers. I can't find any class that seems to fit the right click context menu in the layer panel.

How can I do this?

Luis Perez's answer was what i wanted.
I meanwhile found the way to add actions to the right click context menu, so posting this here for anyone else looking

def printSomething():
    print('Yay a new action!')
    
customAction = QAction('Print Something Nice')
customAction.triggered.connect(printSomething)
iface.addCustomActionForLayerType(customAction,'',qgis.core.QgsMapLayerType(0),True)

This will add the action Print Something Nice to all the Vector layers in your project.

This can be further customized by connecting the action to other signals instead of triggered, like hovered for instance.

This question was answered here Getting Layer Properties of QGIS on standalone application using PyQGIS API

It seems that the layer properties dialog is not accessible via PyQGIS but its individual parts are.

For example, try this on a vector layer, especially as you point out the symbol

layer = iface.activeLayer()
d = QgsLayerPropertiesWidget(QgsSimpleLineSymbolLayer(), QgsLineSymbol(), layer)
d.showPanel()
