Scanning barcodes

I would like to use scan barcode feature in Airtable. I created a form and shared the “shareable” link of the form with another person. But he was not able to scan a barcode with the link on his phone. Only if he logs in to the app and I make him creator or editor, he was able to scan a barcode. Is there a way to make it work with the link because I don’t want to share the base with him.
