Rarible plugin, is it possible to create an auto signature using a private key?

Is it possible to create an auto signature using a private key , Instead of popping up the signature metamask window , When creating a new item and uploading it to rarible.

how do you upload it to rarible?

by moralis server ,
I did everything and it worked, but I don’t want the metamask window to pop up asking for a sign every time I upload new nft

this is my code :


async function setTYhis() {

    const imageFile = new Moralis.File(data.custom_fields.number_photo, { base64: photo })

    await imageFile.saveIPFS();

    let imageHash = imageFile.hash();

    data.image = "/ipfs/" + imageHash

    let metadata = data

    const jsonFile = new Moralis.File("metadata.json", { base64: btoa(JSON.stringify(metadata)) });

    await jsonFile.saveIPFS();

    let metadataHash = jsonFile.hash();

    let res = await Moralis.Plugins.rarible.lazyMint({

        chain: 'eth',

        userAddress: "myAddress",

        tokenType: 'ERC721',

        tokenUri: 'ipfs://' + metadataHash,

        royaltiesAmount: 0, // 0.05% royalty. Optional,

        supply: 1,

        list: true, // Only if lazy listing

        listTokenAmount: 1, // Only if lazy listing

        listTokenValue: 10 ** 16.4, // Only if lazy listing

        listAssetClass: 'ETH' // only if lazy listing  || optional




maybe this helps you, it is not for rarible: https://github.com/dani69654/moralis_opensea_nodejs/blob/main/modules/buyOrder.js
