Icon for Upload component button


I have created a UI with a textfield and Upload component(see the attached figure). And I need an icon(without text) placed inside the button of the Upload component. If I set the button caption to null only image will be visible and Button wont be there !

Is there any way to solve this issue. Please help me !

Where you able to fix the issue?

The Upload-component renders to a file-selection-element in HTML, which cannot be styled or manipulated for good security-reasons. Only workaround is to hide the upload completely and trigger it using the API.
