If you want to allow your users to map their own drives, then by default in the 'manage my drive' feature of Cloud Drive Mapper your users will be able to select from a dropdown list of all the SharePoint Sites, SharePoint Groups and MS Teams they have access to.
However if you do not want your users to be able to select from all of these different types of document libraries, you can restrict the choice of your users.
To do this add a registry key string to:
HKCU or HKLM\Software\IAM Cloud\CloudDriveMapper
This can be added to either the HKLM/HKCU depending how your other CDM GPOs are deployed.
Now enter the string value as follows, based on what you want the users see.
If you want the users to be able to choose from document libraries from two different sources, e.g. SharePoint Sites AND Teams, you can comma delimit the values, as follows:
By default without the regkey, a user's list will be populated by all three sources.
