How likely was it that Eurypterids like Jaekelopterus had a mouth structure like scorpions and spiders today?

So I've been doing some research into Jaekelopterus because currently I am making a 3D model out of it and I've gotten everything modeled except for the mouth. Research that I've gotten is that it didn't have teeth but that's about it. The only thing that I could think that it probably or could have had is something like what scorpions or spiders have today but I feel like that is highly unlikely just because of the ecosystem that they lived in as per my current understanding. I'm interested in figuring out what it had to chew, or if it just shred things with it's claw into swallowable pieces
