Burn Position (remove liquidity)

This is an example of withdrawing all or part of an asset from an existing position in Pangea's pool.

import { ethers } from "ethers";
import {BigNumber} from "@ethersproject/bignumber";

/// concentrated Liquidity Pool Manager address
const poolManagerAddress = "0x000...";

/// web3 Provider (metamask provider / jsonRPC provider / ...)
const provider = ethers.getDefaultProvider();

// burn position
async function burnPosition(
    tokenId:number,  // tokenId
    amount:string,   // amount of liquidity to burn
    recipient:string // recipient address
) {
      const poolManager = await ConcentratedLiquidityPoolManager__factory.connect(positionManagerAddress, provider);
      const tx = await poolManager.burn(
            tokenId, // position ID to remove liquidity from. will burn if all liquidity is removed
            amount, // amount of liquidity to burn. You can get position liquidity size through poolManager.positions(tokenId).
            recipient,
            0, // token0 slippage limit. if removed token0 is less, revert
            0, // token1 slippage limit. if removed token1 is less, revert
            false // Unwrap? "true" if you want to get KLAY instead of wKLAY
      );
      await tx.wait();
