I built a PowerApps SharePoint list form that collects, among other things, image data in a text field as a Base64 string:

I know how I can use a Flow to convert it into a file, and save it on a library, but what I really need is to populate a Word template using directly that Base64 string text without converting into a file first. Is there a way to do this? The images are usually either jpeg or png. Thank in advance.
