create a link of lp editor and try to create prefixes for my groups and they do not work for me I was checking if I wrote it correctly and it was correct then I was changing the color codes also I had to reinstall the plugin and it still did not work for me

LuckPerms does not perform any chat/tablist formatting of its own!

LuckPerms only acts as the source for prefixes / suffixes, it doesn't actually apply them. You need an appropriately configured chat/tablist formatting plugin for them to be displayed. If the values appear correctly when you run /lp user <user> info, LuckPerms is doing its job!
