Hello, I'm working on a digital demonstration to submit for the CSDH 2025 annual meeting as part of Congress 2025. I have filled out the abstract and contribution details, however, I am being prompted to upload file(s). I do not have any files to upload as my digital demonstration is an online exhibition/website. I am not able to proceed with my submission without uploading a file. Do I absolutely need to upload a file? If so, what would you recommend? My username is ctavukciyan and user # is 1627. As well, I signed up to the online conference software with my personal email ctavukciyan@gmail.com Thank you!
