Solved How to check for build access with WorldGuard API

I have a plugin that allows players to instantly destroy items if they have a gold pickaxe in their hand. I need to see if they have access to build so that they can't greif any protected WorldGuard regions. I looked in the WorldGuard API Wiki but nothing was making sense. Here is the code that allows them to instantly destroy blocks.

Code:java

    @EventHandler
    public void playerInteract(PlayerInteractEvent event) {
        Player p = event.getPlayer();
        Block block = event.getClickedBlock();
        Material item = p.getInventory().getItemInHand().getType();
 
        if ((event.getAction() == Action.LEFT_CLICK_BLOCK) && (item == Material.GOLD_PICKAXE) && (block.getLocation().getY() > 0.0D) && (block.getType() != Material.BEDROCK) && (p.hasPermission("instabreak.break"))) {
            block.setType(Material.AIR);
        }
    }

How would I use the API to check if they have access to build? Thanks!

I found another thread with the same answer.
