Script to Add liquidity to liquidity pool on ApeSwap

Im looking for someone to create a script that checks amount of PEAR on a wallet and adds liquidity to the PEAR-BUSD pool on Apeswap (BSC chain)

I tried to script it, but I dont know how to properly generate the values deadline, amountBDesired, amountAMin and amountBMin

Example transaction:
