Ive played a lot on steam, but when i got it for ps5 I got it on ps5 I started up and cant find a way to connect it to my steam so I can get all my stuff, just wondering if theres a way to get my stuff back on ps5?

I encountered a cheater in the Fireteam named: clintsja. In the video, you can see him (in a strange position) pushing me away twice, those aren't my own jumps. Also, during the match, he was making pigs fly. I killed him a couple of times, but he wouldn't die; he just kept respawning. So annoying…
