MVPIf you iquery mesh is correctly set up, sync should occur automatically. To check iquery communication: https://support.f5.com/csp/article/K13690
There is also a bug that you can check if it is related to your installation: https://support.f5.com/csp/article/K43542292
Do you see any relevant message in /var/log/gtm?
