I have been playing the tutorial for a while now and not having any Stellaris experience I was overwhelmed at first and missed out on a few major missions, ie Bajor and the Borg. I just want to confirm but is there any way to liberate Bajor past a certain point? I tried declaring war with the Cardassians which didn't allow me to claim any planets (I figured out after this is a UFP mechanic without going section 31). I don't even see Bajorans on the contacts screen to be able to start the process. Would appreciate any help as otherwise I am stuck on my missions and can't proceed any further, it's basically a waiting game now to finish.
