In HS my son had a lacrosse teammate he was close to hang himself in his back yard. The team was founded by a student how led them to a championship in its second year, and then he killed himself. There was a memorial rock for him at the field. The team gathered around it before every game.
After my son's friend died the school made a typical response ( they had a couple other suicides ). Encouraged everyone to talk about it. Had a big memorial in the auditorium. Kids came on stage and spoke fondly about him who hadn't ever spoken to him. When there was talk about another memorial monument the coach and other parents finally put a stop to it all.
These days with fame, attention and affirmation driving so many of our youth, our reaction to a youth suicide can make it look almost attractive. Whatever leads kids to kill themselves is often complex. But like the mall shooter looking for fame, I think we should not lionize youth who commit suicide. Counseling for survivors, especially fellow youth, should be in private, not via public group displays.
Just my opinion based personal observation and discussion with my sister, a retired HS counselor who went through 6-8 student body suicides.
