I am not able to use the 'reported as unsafe' feature to report a false detection because it requires that I am using the Edge browser in Windows 10 with Windows Defender Smart Screen enabled. I'm a Mac user so I would like to know how I report this without being forced to have Windows, Edge and Windows Defender.
You could probably find an updated Windows 10 PC to file the report on. It’s really not a rare bird. But since you obviously also need to address a malware detection issue, why don’t you use the link that I provided for that:

Hopefully there's an open channel between these two Microsoft units that will allow them to resolve the issue; or not, depending on the outcome of their investigation.
