Change Log:

[+] Added the option to deactivate in specific worlds.
# Here you can block worlds in which you do not want this prefix, you can create others with the same permission to show
different prefixes depending on the world:
blocked-worlds: "worldexample, world_the_end_example"

[+] Added the option to specify the functions for each rank, make sure to assign the default permission, for example.
# permission they will need to use this prefix, this one for example place it for everyone to use
permission: default.prefix

[+] Now it is more flexible, you can create your own confirmations for each world/rank
# you can create/delete/modify your own prefixes.
