How to use, how to go back to the previous screen from left_action_items of MDTopAppBar in KivyMD?

I created an app with a NavigationDrawer and everything work correctely, but the problem is to return to the first screen. I want to go back to the first screen (the Screen with name: 'Screen_*principal') when I click in the arrow-left in the MDTopAppBar in Login_*screen but nothing that I did worked.

I tried a lot of things but nothing work, if someone could fix it I would be very grateful

In your kv, change:
left_action_items: [["arrow-left", lambda *args : setattr(screen_manager, "current", "Screen_principal")]]
to:
left_action_items: [["arrow-left", lambda *args : setattr(root.manager, "current", "Screen_principal")]]
This change accesses the ScreenManager by referencing root.manager, and the root in that context is the Login_screen.

Nav Bar doesn't cover screen when opened

I'm building a registration form screen in Kivy. I have some other basic screens as part of the nav bar. However, this is the first one I'm really adding some content to. I have some round text fields that I've just thrown on there to get an idea of spacing, but currently when I reopen the NAV the bar the text field buttons appear in front of it and I want it to be behind.

Change mouse pointer to 'hand' when hovering over a button of a screen in kivy Python

How can I change the mouse pointer to 'hand' when hovering over a button present in a screen along with a different widget in kivy python?
I tried creating two functions in a python file. But it changes the mouse cursor for the entire page. How can I change the cursor for just the button present on the page?

This are my project files that matter for now, how can i get the .text value from the old_pass textfield in the DashboardGerente class?

I would suggest as follows,
Create a property, say, user_input = StringProperty("") in your App's subclass. then in kv lang of Content class,
MDTextField:
id: old_pass
on_text: app.user_input = self.text
Now use this in any method of DashboardGerente as MDApp.get_running_app().user_input

Prevent KivyMD from drawing a widget several times

I am currently building a mobile app with Python and KivyMD. On my application I have an MDExpansionPanel which is called in the on_pre_enter method of the ScreenManager. Naturally this will cause that every time I enter to the same page, the widget will be drawn once again.
Is there a way to delete the previous widget before drawing the new one? I've tried several approaches however I have had no success.
The code for a minimal reproducible example is the following:
Python code:
