Player name tag hiding using scoreboard team options does not work in version 1.19.2. The most recent version I could get it to work in was 1.17.1. 

Here is the code for creating a scoreboard team and having that team hide nameplates for a given player: (kotlin)

val scoreboard = Bukkit.getScoreboardManager()!!.mainScoreboard

var hidden: Team? = scoreboard.getTeam("nhide")
if (hidden == null) {
    hidden = scoreboard.registerNewTeam("nhide")
    hidden.setOption(Team.Option.NAME_TAG_VISIBILITY, Team.OptionStatus.NEVER)
}
hidden.addEntry(player.name) 

Just switching which version the server runs on, without adjusting any code or re-compiling the plugin, will determine whether or not the nameplate is hidden as it should be (1.17.1) or not (1.19.2).
