Need against with the Timurids

[killerbee256]

I'm playing as the Byzantine empire and I am trying take back Anatolia but the Timurids control the eastern half, how do I get these territories back? Because I am unable to demand them in a peace settlement and and I can't march on the rest of their empire because the Anatolian provinces are isolated from the rest of their empire.
Edit: Hey admin could you fix the typo in the thread title?

You have to occupy the provinces first, then send colonist to establish a colony, just like with unclaimed land. When the colony reaches 1k ppl it defects to you.
Remember to keep troops around cause if the Timmies come back they will burn your colony.
Oh, and you have to stay at war with em to do this

Settle them with colonists. You should see the button saying send when you click on the province.
