how do i act at a concert?

im absolutely going to the hanl concert in my city, but it's my second time going to one and the previous one (pierce the veil) i was just kinda standing around lmao, i was also recording like every song which i get now is kinda annoying, but i just want to know what to expect since i can imagine hanl is much more the mosh pit type of show and im a little antisocial so it's a little anxious thinking about it 💔💔
