How to make embedded Jpanel go to WEST

Im creating an application in java swing and in it Im making what I think is called an embedded Jpanel which is to my understanding a jpanel inside a jpanel. To make this simpler we will use the panel names there is content, sidebar, and content sidebar

Sidebar is just the sidebar for the application with buttons

Content is the main content of the app

Content sidebar is a side bar inside of content, I use this so my settings page has its own side bar apart from the normal side bar.

I make sidebar aligned to WEST and content CENTER

after content.add(contentSidebar, BorderLayout.WEST); it won't make content sidebar go to west and im not sure why.

this is my source code

package Assets.Settings;

import javax.swing.*;
import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

public class Security implements ActionListener{
    JFrame Security;
    JPanel sideBar;
    JPanel content;

    //for sidebar
    JButton volume;
    JButton security;
    JButton contactUs;

    JPanel contentSidePanel;
//    JButton twoStep;
//    JButton changePassword;


    public void security(){
        Security = new JFrame();
        sideBar = new JPanel();
        content = new JPanel();

        contentSidePanel = new JPanel();

        sideBar.setPreferredSize(new Dimension(125, 700));
        content.setPreferredSize(new Dimension(1000, 700));

        content.setBackground(Color.YELLOW);

        Security.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        Security.setTitle("Anonyomail Security Settings");
        Security.setSize(1152, 700);
        Security.setLayout(new java.awt.BorderLayout());

        contentSidePanel.setLayout( new java.awt.BorderLayout());

        volume = new JButton();
        security = new JButton();
        contactUs = new JButton();

//        twoStep = new JButton();
//        changePassword = new JButton();

        volume.addActionListener(this);
        contactUs.addActionListener(this);

        volume.setText("Volume");
        security.setText("Security");
        contactUs.setText("Contact Us");

//        changePassword.setText("Change Password");
//        twoStep.setText("2-Step");

        security.setBackground(Color.decode("#24a0ed"));

        



        contentSidePanel.setPreferredSize(new Dimension(100, 700));

        contentSidePanel.setBackground(Color.BLACK);

//        contentSidePanel.add(changePassword);
//        contentSidePanel.add(twoStep);

        content.add(contentSidePanel, BorderLayout.WEST);

        sideBar.add(volume);
        sideBar.add(security);
        sideBar.add(contactUs);


        Security.add(sideBar, BorderLayout.WEST);
        Security.add(content, BorderLayout.CENTER);

        Security.pack();
        Security.setVisible(true);
    }

    @Override
    public void actionPerformed(ActionEvent e) {
        if(e.getSource() == volume){
            //open volume
        }else if(e.getSource() == contactUs){
            //open contact us
        }
    }
}

EDIT

The issue is that I didn't give content a border layout
