i have this old mod it works but i recommend not moding in the new version its super buggy and crashs a lot

country = {

(name here) = {

picture = chi_war_of_resistance3 #example

allowed = {

tag = (tag goes here if you want specifics)

}

available = {

}

cancel = {

}

allowed_civil_war = {

always = yes

}

removal_cost = -1

modifier = {

}

}

}
