Crossplay between ps5 and pc steam ASE

I want to play ark with my friends on the same server but I’m not sure how to do it. There’s a lot of questionable information (especially when i can’t distinguish whether someone’s talking about ase or asa) on the internet and I’m not all that tech savvy, unfortunately.

I have ark on my ps5, while my friends have ark on pc (steam). Firstly, is crossplay even possible?

And if it is, what is the best way for us to play together on a server? I know that I need to pay for ps plus. I thought that’d be it but then I saw other things that we also apparently need to pay for? I’m not sure what’s true and what’s not, pleaseeeee help🙏🙏🙏🙏🙏
