ExecuteOnRunning doesn't seem to do anything

[Marvin-Brouwer]

I have the following setup:

			builder.UseContainer()
			.UseImage("mcr.microsoft.com/mssql/server:2022-latest")
			.WithName(imageName)
			.WithHostName("sql")
			.WithEnvironment(
				@"ACCEPT_EULA=Y",
				$@"MSSQL_SA_PASSWORD={options.SaPassword}",
				@"MSSQL_PID=Express"
			)
			.AsUser("root")
			.CopyOnStart(createDbScriptPath, @"/src")
			.UseWorkDir("/src")
			.ExecuteOnRunning(dbCreateScripts.ToArray())
			.AsUser("mssql")
			.ExposePort(options.Port, 1433)
			.UseIpV4("127.0.0.1")
			.DeleteIfExists(false, true)
			//.WaitForProcess("/opt/mssql-tools/bin/sqlcmd")
			//.WaitForPort("1433/tcp", TimeSpan.FromSeconds(10))
			.WaitForMessageInLog(
				"Recovery is complete. This is an informational message only. No user action is required."
			);

The dbCreateScripts.ToArray() contains a couple of commands but one of them is to simply touch a file so I can see if it works.
I get no errors, yet no file appears. And, I can see the other commands aren't executed too.

What am I doing wrong here?
