Terraform Providers Azure

Hi

I have 5 FunctionApps with One AppServicePlan[Premium] .
One VNET with one subnet already there[Not to be created], which to be used with FunctionApp along with storage.

When I try with azurerm_app_service_virtual_network_swift_connection it can not integrate all funcion apps.

Any solution for same or may be any code example link.
