NPC Secondary approvals for Isabelle

[Isabelle]

I know most of that, I'm just asking more detail on the non-OC approvals process which aren't mentioned in the rules at all. I mean, where did he get that form? It's different form the NPC Primes one which is just the join app. Do I need to get moves approved for them separately like NPCe Primes or is there more leniance like with every single other NPC secondary?

I mean, I can't find information on this anywhere.
