faild to detect local data base from client pc c# windows application

I have a simple windows forms app (C#) in development, and I am just trying to test to see that I can publish it for others to use, It has a local Database, and it is utilizing Microsoft SQL Server Database File (SqlClient). I tried publishing what I have (so far) to myfriend pc. when he opened the app this error came out to me and he couldn't access to app local database

and this the app.config

<configuration>
<configSections>
</configSections>
<connectionStrings>
    <add name="sell.Properties.Settings.DatabaseConnectionString"
        connectionString="Data Source=(LocalDB)\MSSQLLocalDB;AttachDbFilename=|DataDirectory|\Database.mdf;Integrated Security=True"
        providerName="System.Data.SqlClient" />
</connectionStrings>
<startup> 
    <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.7.2" />
</startup>

using (SqlCommand cmd = new SqlCommand("insert into ProductTbl (Id,Nom,Quantité,Prix,Catégorie,Photo) values (@prodid , @prodnam, @prodqyan ,@prodprix,@prodcat,@pictur)", con))
