When I add the UPLOAD FILE option into a form, the types of files that can be uploaded are not displayed in preview mode. They will only be displayed if you manually enter what's allowed. Sometimes, not allowed file types can be uploaded. Further, the background and text colour of the upload field can not be changed. It would be great if there was the option to customise the colour pallet of this field. I created a video showing the problem: https://www.loom.com/share/22ec29745d03430c9059ba1071100740?sid=2518c633-0465-42bf-a42a-2d12e4d19ebe
