How do I set a hero limit for the AI?

Let's see) For now, I'm working on a dynamic multiplayer map where the action will take place in a very large city. Until recently, I was preparing a spin-off map for Unicorn Empire, but unfortunately, due to technical issues, I lost most of my personal data, including everything related to games. Therefore, for now, I'm doing a little bit of everything: building a map, restoring mods, and re-populating the Lua file to bring back convenient and interesting functions. That's it... If anything comes out of me, you'll definitely know)
