Redefined Glowing Entities

Redefined Glowing Entities is an API for developers to make entities glowing.
Supported Minecraft versions: 1.17+
Dependencies: PacketEvents
Since it uses teams to set glowing color, you can also set nickname visibility and collisions.

Example usage (this is your main class implementing listener):

public RedefinedGlowingEntitiesAPI geAPI;

@Override
public void onEnable() {
	geAPI = new RedefinedGlowingEntitiesAPI(this);
	getServer().getPluginManager().registerEvents(this, this);
	// rest of your code
}

@EventHandler
public void onEntityInteractEvent(PlayerInteractAtEntityEvent e) {
	if(!e.getHand().equals(EquipmentSlot.HAND))
		return;

	Entity rightClickedEntity = e.getRightClicked();
	Player player = e.getPlayer();

	geAPI.setGlowing(player, rightClickedEntity, NamedTextColor.GREEN);
	geAPI.setNametagVisiblity(player, rightClickedEntity, GlowTeamNametagVisibility.NEVER);
	geAPI.setCollisionRule(player, rightClickedEntity, GlowTeamCollisionRule.NEVER);
}
