Content Library sync between different VCenters not linked

[alpatio]

Hello,
I'll have 2 different VCenters (vSphere 7.0) from different organizations of the same customer that are located on different sites, and each one was configured with their own SSO. But are using the same templates, now we are copying templates time to time manually as these VCenters aren't linked

Does is possible use content Library to sync templates between both VCenters with the current configuration? (For some other reasons I'm not allowed to link between vCenters)

I've tried to create a remote-content lib definition with password protected library, I don't have any errors, but nothing is synced ....

Any advice ? 
Thanks in advance

It should work for OVF Templates. But for VM templates there is limitation:

"The distribution of VM templates additionally requires that the respective vCenter Server instances are in Enhanced Linked Mode or Hybrid Linked Mode and that the respective hosts are connected through a network."
