Received trial license but I can't install it in VS Code on Win 10

I got a trial license.txt. But I can’t install it. The instructions mention a notification I can click on to load the license. There is no notification to click on. The instructions mention using Install-PostProToolsLicense. PowerShell says: The term ‘Install-PoshProToolsLicense’ is not recognized …
Just stuck with none of the Pro features enabled, so I have no idea if I’ll be able to try this product for real.

I found a way. Just to the right of IntelliSense in the lower right was a little icon that looked like two paper clips attached to each other. I clicked on that, and that’s where I was able to find something that said Install License.
