How to get courses from the garmin connect website to the 67i?

I have alltrails, I use that to export a trail to garmin connect. I can see the trail on the website under my courses. I send to device, opening the garmin express app on my pc, the device syncs. I then disconnect my 67i, but I can not find any trails, courses, or anything. I do not want to use the device to plot all my trails', how am I supposed to use courses from garmin connect?!
