Where does master.dacpac come from in VS 2019?

We have some build tasks that run and for the life of me I can't figure out why the ms build tools isn't installing the master.dacpac file needed for the master and system dacpac files. Here's where it lives now:

:\Program Files (x86)\Microsoft Visual Studio\2019\Professional\Common7\IDE\Extensions\Microsoft\SQLDB\Extensions\SqlServer\150\SQLSchemas

Currently, in VS2019 Professional it is added with the Data Storage and Processing Workload. SQL Server Data Tools is a dependency for several other workloads, such as: - ASP.NET and web development - ASP.NET and web development tools - Azure Data Lake and Stream Analytics Tools - Cloud tools for web development In MS Build Tools, I noticed that the dacpac file isn't generated after installing the Data Tools workload. Am I looking in the wrong place? What is generating the master.dacpac and the system.dacpac in C:\Program Files (x86)\Microsoft Visual Studio\2019\Professional\Common7\IDE\Extensions\Microsoft\SQLDB\Extensions\SqlServer\150\SQLSchemas?
