ASP.NET Core - cannot "dotnet ef database update" to migrate, but CL throws "CREATE DATABASE permission denied in database 'master'."

I am trying to create a database and connect it with my ASP.NET Core app.

I am using Mac, so the setup I followed is this tutorial, https://www.ciclosoftware.com/2018/03/14/sql-server-with-net-core-and-entityframework-on-mac/

When I use "dotnet ef database update" in my command line, I get errors saying

Failed executing DbCommand (19ms) [Parameters=[], CommandType='Text', CommandTimeout='60']
CREATE DATABASE [FileDB];

CREATE DATABASE permission denied in database 'master'.

I was trying to find a way to give a permission to the master, but could not find the solution for Azure Data Studio for Mac os.

Could somebody help me?
