why Visual studio 2019 missing SQL Service-Based-Database

I am trying to make a Login form in visual studio and I watched few videos and it says that I need to use the SQL server data tool/Service-Based-Database in the solution item section but seems like it's not there. I already checked and it is installed already, anyone knows what I'm doing wrong or what other step should I take?

This is what I am looking for exactly:

You are trying to add a "Solution Item" - you likely right clicked on your Solution in solution explorer, rather than one of your projects. If you right click on your actual project in solution explorer and attempt to add an item, you should be able to see the Service-based Database.

So do one of the following:

• Right click on your project in solution explorer and select Add → New Item. Then find the Service-based Database item.
• Left click on your project in solution explorer to select it, then in the top menu bar of Visual Studio, click the Project menu item, then Add new item and find the Service-based Database.
