Can not see deployed factory on openSea when deploying it to matic mumbai testnet.

[chahakshah111]

Hey, when i deploy factory on rinkeby network I can see it on openSea testnet version, but when I deploy it on matic mumbai testnet I'm not able to see any factory on openSea. But I can call any function on factory like mint.
What could be the issue. Does openSea support factory for matic mumbai network

same problems.

Finally, I added the function:

function supportsInterface(bytes4 interfaceId) public view virtual returns (bool)

such as:

    /**
     * @dev See {IERC165-supportsInterface}.
     */
    function supportsInterface(bytes4 interfaceId) public view virtual override(ERC165, IERC165) returns (bool) {
        return
            interfaceId == type(IERC721).interfaceId ||
            interfaceId == type(IERC721Metadata).interfaceId ||
            super.supportsInterface(interfaceId);
    }

or

    function supportsInterface(bytes4 interfaceId) public view virtual returns (bool) {
        bytes4 _ERC165_ = 0x01ffc9a7;
        bytes4 _ERC721_ = 0x80ac58cd;
        bytes4 _ERC2981_ = 0x2a55205a;
        bytes4 _ERC721Metadata_ = 0x5b5e139f;
        return interfaceId == _ERC165_ 
            || interfaceId == _ERC721_
            || interfaceId == _ERC2981_
            || interfaceId == _ERC721Metadata_;
    }
