How can I apply a new Maven archetype to an existing project using CommandLine?

  archetypes, java, maven, terminal, windows

There is a similar thread already from a couple of months back, but it does not seem to resolve my issue. I have a new, updated Maven archetype and I need to "apply" it somehow to an existing project.
I know it can somehow be done with a Maven command line, but I searched the internet for hours and can’t seem to find any solution.
As a matter of fact, I don’t even know how to do it "manually", without any terminal.
I am using Windows 10 and Intelij.

Please, help.
