How ERC20 token set tax mount when buy/sell on Pancake Swap?

Question

I created ERC20 (just basic with Openzepplin), I can add liquid to Pancake. Buy, what I need is:

• When users buy token on Pancake, I need to transfer 3% amount BNB to Owner Address.
• When users sell token on Pancake, I need to transfer 3% amount Token to Owner Address.

I've research and found that: in function _transfer, we can detect from/to is pancake pair address, then we know client is buying or selling. Buy I dont know how to transfer tax to another address (ex Owner address).

Thank you.

You can make the transfer function to payable and write your logic in to transfer the percentage.
