I've created a bunch of new group policies on different networks using create_network_group_policy. I tried to specify vlan tags when doing this, but when I checked none of them had vlan tags assigned. I would like to assign a vlan tag to each policy through the API but the documentation says I need the group policy ID in order to use update_network_group_policy. I don't see anything in the web interface indicating an ID but the name of the group policy doesn't seem to work. Since the organizations and networks all have long ID numbers (ex. L_616993148949760000), I'm wondering if these group policies also have ID numbers that I need in order to update them. If that's the case how would I find out what they are? If it's not the case what's the correct syntax to use with this update_network_group_policy when specifying a vlan tag?
