/team problem

First off, I'm on 1.19 java papermc.

Was coding a team command for my server but the team won't show up in chat.
This is what i have been coded:

/team add troll
/team join troll mikaeloverby
/team modify troll prefix {"text":"[TROLL] ","color":"dark_green"}

Everything works just fine but it wont show up in chat. that's because im not in vanilla but papermc.
Went to the config on FTP to change use-vanilla-world-scoreboard-name-coloring, from false to true as it should fix the problem.

Here's the problem:
I can not find paper.yml file but bukkit.yml and spigot.yml

Does that mean I'm on bukkit/spigot server and not papermc? The world says "papermc-1.19-b14" today as we're now on 1.19.

Any help or solution for this problem?
