Microsoft Dyanmics 365 Online Plugin to call SharePoint Online CSOM code

Hi,

I'm doing researching in coding for Microsoft Dyanmics 365 Online Plugin to call SharePoint Online CSOM code. It seems that all the posts online saying it will not work.

“Microsoft.SharePoint.Client.dll” and “Microsoft.SharePoint.Client.Runtime.dll” While registering the plug-in, merging these libraries with the plug-in will not work. Unless to write REST method to connect to SharePoint online.

Can any one confirm this?

Thank you.
