Looking for JS export with FontFace loading raw content as parameter

1. We have a REST API which are secured, and we can get the File content as a response by calling the API. These responses are WOFF & WOFF2 file formats. 2. We need to inject response object into @FontFace or using JS New FontFace() and load the content into Fontfaces so that we can it in the HTML. 3. It works fine by giving the direct SRC link (without Authentication), but we need to send Header parameters with Authentication token to pull it (when we are using directly instead of sending as a content). 4. We need JS export who can solve this.
