The release notes for Polycom UC software 5.9.4 indicates support for OAuth, but it seems that version is not on the approved list for Skype For Business Online implementations. Customers in Skype for Business deployments should only use software releases that have been qualified by Microsoft or the maintenance releases built on a qualified release. The current version which is qualified by Microsoft is 5.9.0.9373. When will Microsoft qualify the release version 5.9.4? both the below URL's from Poly and also Microsoft suggests us to stay in 5.9.0.
