Cooldown on levy style powers

Age of Empires III: DE III - Modding
1

So i am trying to add the ability for native civs to have a levy style big button in the mold of Hausa’s Songhai levy raiders tech

I have made it so that the button works, have the cost and spawn units at the TC

but…

there is no cooldown for some reason even though i effectively copied how songhai button works

Am I missing something??

Also from what I can tell these only allow you to spawn 1 kind of unit, if anyone knows how to make it so that it spawns like a group of units pls let me know ( i guess kinda like how banner armies work)
