Read Connection String from App.Config in VB.Net

Dear Sir

I'm Trying to save from the DbContext module to the config connectionstring and call the config connectionstring in DbContext module with VB.NET

Please Guide me

Thanks

So I want to save the connectionstring from the below module to the application config

Imports System.Data.OleDb
    Public Module DbContext
        Public Function GetOledbConnectionString() As String
            Return "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=|DataDirectory|\WAREHOUSEGB.accdb;Persist Security Info=False;"
        End Function
        Public Function GetOledbConnectionStringgoogledrive() As String
           Return "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=G:\My Drive\MASTERITEMBORDIRFINAL.accdb;Persist Security Info=False;"
        End Function
 End Module
 Public Function GetConnection() As OleDbConnection
Return New OleDbConnection(GetOledbConnectionString())
 End Function

 Below is the connection string code in each of the classes I call from the dbcontext module so how can I call it can be called directly from the config application

Public Class SizeProductService

    Private ReadOnly _conn As OleDbConnection
    Private _connectionString As String = DbContext.GetOledbConnectionStringgoogledrive()
    Public Sub New()
        _conn = New OleDbConnection(_connectionString)
    End Sub
End Class
Public Class StocksinService

 Private ReadOnly _conn As OleDbConnection
    Private _connectionString As String = DbContext.GetOledbConnectionString()
    Public Sub New()
        _conn = New OleDbConnection(_connectionString)
    End Sub
End Class

Public Class UserDao

Public Function Login(ByVal username As String, ByVal password As String) As User
    Using connection = DbContext.GetConnection()
        connection.Open()
    End Using
End Function

let me know if anything is not clear

Thanks

The app.config becomes like this

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <configSections>
        <sectionGroup name="applicationSettings" type="System.Configuration.ApplicationSettingsGroup, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" >

        </sectionGroup>
    </configSections>
    <connectionStrings />
    <startup>
        <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.8" />
    </startup>
    <applicationSettings>
        <WindowsApplication23.My.MySettings>
            <setting name="conString" serializeAs="String">
                <value>Provider=Microsoft.ACE.OLEDB.12.0;Data Source=|DataDirectory|\WAREHOUSEGB.accdb;Persist Security Info=False;</value>
            </setting>
            <setting name="conStringGoogleDrive" serializeAs="String">
                <value>Provider=Microsoft.ACE.OLEDB.12.0;Data Source=G:\My Drive\MASTERITEMBORDIRFINAL.accdb;Persist Security Info=False;</value>
