Maybe this has changed a while ago, as I have not done this in over a year. However, I can neither view nor edit heart rate zones in Garmin Connect Web. I have a Forerunner 920XT. I can edit on my watch under My Stats > User Profile > Heart Rate Zones, but cannot view on GC Web. IIRC, I would click on my device > Device settings > User Settings tab. I would be able to view and edit heart rate zones based on %Max or %HRR or custom entry. I typically use Edge Chromium, but I also tested in Google Chrome and Firefox with the same result. I have tried syncing with Garmin Express, restarting my watch and my Android phone. Now all I see is Power Zones I don't even know what that is. Is it a cycling metric?
