My clients cannot view form submission from their email

Hey guys,
Does anyone know why my client can’t view form submission from their email.
It literally comes up with {“msg”:“You are not currently logged in”,“code”:401,“name”:“Unauthorized”,“path”:“/api/sites/magnetiq-events/formUploads/8efbadd5-022a-4eff-965b-3d5d3249721e.png”,“err”:“Unauthorized: You are not currently logged in”}

How can I give my clients authorization? without them having to log into the editor?
