My users have the default 'Read' permissions set on SharePoint online, but the option to sync a document library is not available for them. What is the minimum required permission level to be able to sync a document library?

You must either give the following persmission:
- Use remote interfaces
- Use Client Integrations features
If you disable the ‘Limited-access user permission lockdown mode’ feature via ‘Manage Site Collection Features’ at the site collection level, the problem is also solved.
