Hi, i'm currently try to use USDC token to buy/sell NFT, and for that i need to approve my NFT Contract to be able to use transfer function

My wrote this part of the code :

function getApproval(uint256 _pid) public returns(bool){

    TokenInfo memory tokens = AllowedCrypto[_pid];
     IERC20 paytoken;
     paytoken = tokens.paytoken;
     uint256 cost;
     cost = tokens.costvalue;

     paytoken.approve(address(this), cost);
        
}

but it doesn't seems to work as expected, in didn't approve anything and it's impossible to use USDC this way... I con't find my mistake,

if someone as the answer
