hello, I have a problem, I want to execute this command in a command block "/ rg addmember (region) @s". It doesn't work in any way. but the "warp (site) @s" command works perfectly. I can't find the reason why it doesn't work. My idea is that when you step on a pressure plate, players are automatically added to the region. Does any plugin solve this? I await your answers, thank you!
