[DaftFunk123]

SpongeAPI version: spongeforge-1.12.2-2838-7.2.1-RC4011.jar

PlaceholderAPI version: PlaceholderAPI-4.4.jar

Plugins installed: holograms-3.1.5.jar, HologramsPlus-1.0.0.jar, LuckPerms-Sponge-5.0.39.jar

Description: I'm wondering how I might make my own placeholder or javascript file that can retrieve the value of any minecraft scoreboard objective for a specific value??? Because I would like to use this to post the scores on a hologram using the plugins I have installed.
