How to Display an Application Window Below Other Windows with SYSTEM_ALERT_WINDOW?

I have used the `WindowManager.LayoutParams.TYPE_APPLICATION_OVERLAY` and `WindowManager.LayoutParams.TYPE_PHONE` attributes to create an overlay for my application. However, I don’t want it to appear above all other windows. Instead, I want it to behave like with the settings window, where it remains underneath other active windows. How can I achieve this?

my code:

params = new WindowManager.LayoutParams(
        WindowManager.LayoutParams.WRAP_CONTENT,
        WindowManager.LayoutParams.WRAP_CONTENT,
        WindowManager.LayoutParams.MATCH_PARENT,
        WindowManager.LayoutParams.MATCH_PARENT,
        Build.VERSION.SDK_INT >= Build.VERSION_CODES.O ?
                WindowManager.LayoutParams.TYPE_APPLICATION_OVERLAY :
                WindowManager.LayoutParams.TYPE_PHONE,
        WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE,
        PixelFormat.TRANSLUCENT);
params.gravity = Gravity.TOP | Gravity.LEFT;

Right now, the overlay appears on top of other apps, like here:

I want it to look like this, where it disappears when another app is opened:
