I need to restrict the user to upload only the file extensions that i mentioned in the Allowed file extensions filed. It works properly. But in front-end, i need to add a comma separator for this format.
Actual - Allowed file types: ai aif avi bmp csv doc docx eps fla flv gif img.
Expected - Allowed file types: ai, aif, avi, bmp, csv, doc, docx, eps, fla, flv, gif, img
