Upload file to monday.com - working from Postman, not working from Client

Hi all,

I am new to monday.com and also to GraphQL, so I had to figure everything from scratch.

Currently I am developing app, where I need to upload file to specific database column.
Columns looks like this:

files_1 : {
    id: "files_1",
    text: "https://something.monday.com/protected_static/ID/resources/ID2/image.jpg",
    title: "Dedication Image",
    type:  "file",
    value: (JSON.stringify value of text...)

When I want to access photo and display it on web, I need to query with assetID and then I receive publicURL.
That was for querying.

What I need is upload file from web to monday.com

I triend every single solution that I had in mind or I found on google, but nothing helps me.

Here is my function for uploading picture:

        var formData = new FormData();
        formData.append("query", `mutation addFile{add_file_to_column (item_id: 3286592696, column_id: files_1, file: ${file}) {id}}`);
        formData.append('map', '{"image":"variables.file"}');
        formData.append('image', file);

        res.json({ response: formData });

        const config = {
            headers: {
                'Content-Type': 'multipart/form-data',
                'Authorization': token

        await axios.post(url, formData, config)

This is same query as from Postman, where it works without problem. How can I send this query from my client?
Every single request ends with CORS problem.

I am using React.js (Next.js) with antDesing.

Thank you
