Best way to sync Connect - Strava - Xert

What is the best way to set up Xert syncing with Strava and / or Garmin Connect? I use Garmin devices witch send ride info to Garmin Connect witch synchronizes my rides to Strava. Now I ad Xert but not clear if I should sync Xert with Strava or Garmin connect or both. If I use both don’t I get the ride double in Xert?
