Serial Port Helper VS Code extension help

After reading Getting Started - Serial Printing in the libDaisy docs I installed the Serial Port Helper extension in VS Code, but nothing comes up in the list of ports. I suspect it’s a configuration thing I’m missing, but I’m getting nowhere trying to figure it out.

Is anyone using this with Daisy Seed successfully? According to the docs, “Serial Port Helper extension for VS Code is simple to use, and works great with Daisy.” Any help would be greatly appreciated.
