No, we do not support M365 home plan accounts.
The backup of organizations under M365 business plans alone are supported as they are part of an exchange environment and have exchange licenses. Hence, the data under "Emails, Contact, Calendar & Task" are backed up. Additionally, if any users in an organization have a OneDrive license, then OneDrive Data is also backed up. Once the Global Admin of an M365 business plan tenant authenticates, then the backup of the tenant data (SharePoint, Groups & Teams) is also created.
