Allow move/copy from O365 Group to any O365 Sharepoint Library
Currently you can create an Office 365 Group for a project and it comes with a "Files" section to share files. Well, the group's project is done and you want to move or copy those files to a more public repository on Office 365 Sharepoint. However, there is no may to multi-select files/folders and move/copy from the Groups to Sharepoint. This is a huge need as it exposes the file to the whole company for discovery whereas Groups are usually a limited audience. If you are a Mac user, you don't have the Windows Explorer option either. This should be easy and all web based on every browser.

You can try 3rd party SharePoint Migration tool (https://www.nucleustechnologies.com/sharepoint-migration/) to perform migration between Office 365 to SharePoint.
