How to send ether to erc721 token owner?

I want to send ether to token owner.

ownerOf returns address, so I set payable address inside of sendEther function.

However, error says 'Type address is not implicitly convertible to expected type address payable'.

Is there any way to set payable address inside function? Could you give me any advise?

  function sendEther(uint256 _tokenId) public payable {
    address payable _tokenOwner = ownerOf(_tokenId);
    _tokenOwner.transfer(msg.value);
  }

ERC721.sol
    function ownerOf(uint256 tokenId) public view returns (address) {
        address owner = _tokenOwner[tokenId];
        return owner;
    }

You can't directly cast from address to address payable, but you can cast in two steps, through uint160:

address payable _tokenOwner = address(uint160(ownerOf(_tokenId)));
