Is it possible to create a Database in SQL Server with powershell?

I am trying to create a empty database in SQL server using powershell and SMO but cannot seem to find a way of doing it. Is this possible?

Connection script for sql

This script replicates the entire default database creation T-SQL in SQL 2016:
