This extension doesn't work. To start with: based on the screenshots, the description and name are wrong. The goal of this extension is to download *activities*, not workouts, which are a different thing in the Garmin system. I tried it on the page for a workout, the list of workouts, the page for a cycling activity, the page for a strength/weights activity, and the list of activities. On all pages, it just says "Sign in or refresh the page to download workout data." No matter how many times I do exactly that.
