   You will need to provide the **Application (client) ID**, **Directory (tenant) ID**, and **Client secret** for the Entra ID app registration that has access to the target OneDrive account, and 
   the app registration must have the correct set of Microsoft Graph access permissions. These permissions include:
 
   - `Files.ReadWrite.All` (if both reading and writing are needed)
   - `Sites.ReadWrite.All` (if both reading and writing are needed)
   - `User.Read.All`
   - `Directory.Read.All`
