Solidity function help needed

Hello guys,
I'am very new in solidity and coding, so does somebody have experience in constructor below? I need to deploy the contract and compiler test is ok but when I want to deploy it on test nest to make sure everything works It asks me to give so value in _A and _DATA, so please let me know how to deploy it, Thanks in advance

        assert(KEY == bytes32(uint256(keccak256("eip1967.proxy.implementation")) - 1));
        (address addr) = abi.decode(_a, (address));
        StorageSlot.getAddressSlot(KEY).value = addr;
        if (_data.length > 0) {
            Address.functionDelegateCall(addr, _data);

Dont even think about it. Nint
