Android Question How to block the top notification bar in Android 11 and above?

[Pure Game]

Ok, I will explain because it could be weird, but I code an Application to help paperboy to be track on a map, so the manager can find him to restock and find easily at the end of the day.
So we install the app on our phone with a ID and at the beginning of the day, we give a phone to every paperboy. But, we don't want him to go in the status bar and remove the network or the positioning. In the passed I used this:

You will need to add those permissions into your Manifest:

AddPermission(android.permission.SYSTEM_OVERLAY_WINDOW)
AddPermission(android.permission.SYSTEM_ALERT_WINDOW)

in the Activity:

#Region Code to disable access to the StatusBar

Sub AddOverlay
Dim mView As Label
mView.Initialize("")
mView.Text = Sentence
Dim mlp As JavaObject
Dim vtype As Int = -1, pixelFormat As Int = -3
mlp.InitializeNewInstance("android.view.WindowManager$LayoutParams", Array(vtype, 100, 2010,296, pixelFormat))
mlp.SetField("gravity", Bit.OR(Gravity.TOP, Gravity.CENTER))
Dim windowManager As JavaObject = GetContext.RunMethod("getSystemService", Array("window"))
windowManager.RunMethod("addView", Array(mView, mlp))
End Sub

Sub GetContext As JavaObject
Return GetBA.GetField("context")
End Sub

Sub GetBA As JavaObject
Dim jo As JavaObject
Dim cls As String = Me
cls = cls.SubString("class ".Length)
jo.InitializeStatic(cls)
Return jo.GetFieldJO("processBA")
End Sub
#End Region

But in Android 11 it is not working anymore. what I can do now?
