When setting up the Staffbase News Sync template for Power Automate, you need to grant edit permission to the SharePoint account. The Power Automate flows use the SharePoint account to fetch SharePoint news for the sync. 

1. In the SharePoint site, navigate to Settings > Site Permissions. 
2. Click Share site.
3. Enter the account holder you want to provide edit permissions.
4. Click the profile and select Edit.
   
   
5. Click Add.

You have provided edit permissions to the SharePoint account connected to the Power Automate flows.
