Coop question about Tech-priest

[Araon]

So I know that the tech priest doesn't have access to the base Martyr campaign, but does that extend to coop? As in - if I create a regular martyr character, would a friend that created a Tech-priest be able to join me on my campaign missions?

And beyong that, I am assuming that all the non-campaign missions are the same for any class, meaning me and a friend would be able to play any of the non-campaign missions together without issue? Please do correct me if I'm wrong :P

Oh, and forgot to ask the vice-versa - as in, can I as a martyr character join coop for the Tech-priest exclusive campaign missions.

The tech adept gets a 7 mission "tutorial" that non-tech adepts can't play and where multiplayer is not available.
They then enter the Prophecy campaign which is basically the second half of the story.
If a non-TA character has progressed their campaign to the point (finished Martyr chapter 5) they can continue the story together.
TAs can't join on story missions prior to that point, meaning the MArtyr campaign is unavailable to them even in coop.

Yeah, I've scoured the internet for more info coz tbh this is usually explained in a very convoluted way - cheers for putting it blunt and simple btw.
Probably the most idiotic design choice I've ever seen in a cooperative game

This is one of the reasons I had to abandon my Tech Adept - hilariously bad coop design!
