[Vuejs]-How to send multiple byteIO files from Flask endpoint to Vue using axios and file encoding

I was able to solve the problem. The following axios request does the trick.
This question was very helpful: Creating a BLOB from a Base64 string in JavaScript

// axios request + file download
        axios({
          url: 'docx/multiple',
          data: {body: body_array},
          method: 'POST',

        }).then((response) => {
          response.data['result'].forEach((element) => {
            console.log(element)

            // decode string to blob --> solution to question
            const byteCharacters = atob(element);
            const byteNumbers = new Array(byteCharacters.length);
            for (let i = 0; i < byteCharacters.length; i++) {
              byteNumbers[i] = byteCharacters.charCodeAt(i);
            }
            const byteArray = new Uint8Array(byteNumbers);
            console.log(byteArray)

            const url = window.URL.createObjectURL(new Blob([byteArray]));
            const link = document.createElement('a');
            link.href = url;
            link.setAttribute('download', 'test.docx');
            document.body.appendChild(link);
            link.click();
          });
});
