my friend got scammed in roblox

Hi everyone. sorry for my English, i using translator. My friend was recently scammed in Roblox. Someone took all her weapons in Murder Mystery 2. I wasn't there at the time and I don't know the whole story, but I want to help her. Are there any working ways to hack someone's Roblox account? I've heard of several methods using cookies or something like that, but I think most of them are scams. I tried to find tutorials in internet, but I didn't find anything useful. I just want to help my friend because she's upset
