How to create a playable government in exile ?

Hello.

Like the title says, I want to create a mod where you play Abdelkrim's rebellion against Spanish's colonization of Morroco in the 1920's. It was a guerilla warfare, and I plan on making it a bit like Free France mixed with PRC with like sabotage operations, offmap factories, etc... and PP operations abroad.

the country will have vanilla cores, I don't intend on modding the states, so it's only the government in exile with the French protectorate of Morocco (kinda like Vichy for France) that bothers me.

EDIT : I forgot the question... How do I create a playable government in exile at the start of the game ? It won't be clickable on the map, I'll have to make it a highlited country
