                             --resource-group
                             [--identity]
                             [--key-identity]

                             [--tags]. The 1th example of the child command would be to use it to 'fluidrelayserver_create', the syntax is: az fluid-relay server create -n TestFluidRelay -l westus2 -g MyResourceGroup --sku standard --tags category=sales --identity type="SystemAssigned"
az fluid-relay server create -n TestFluidRelay -l westus2 -g MyResourceGroup --sku standard --tags category=sales --identity type="SystemAssigned, UserAssigned" user-assigned-identities={"/subscriptions/00000000-0000-0000-0000-000000000000/resourceGroups/MyResourceGroup/providers/Microsoft.ManagedIdentity/userAssignedIdentities/id1","/subscriptions/00000000-0000-0000-0000-000000000000/resourceGroups/MyResourceGroup/providers/Microsoft.ManagedIdentity/userAssignedIdentities/id2"}. The parameter '--name --server-name -n' is required. It is used to the fluid relay server resource name.. The parameter '--resource-group -g' is required.
