Unable to Configure Delivery Channel for Pre-Built OFSC Email anymore

Summary:

About 3-months ago, we were able to configure the pre-built OFSC Email as a Delivery Channel in our lower environment without any issues.

As we are now preparing to configure it in the Production environment, I can no longer save the OFSC Email configuration because the system is requiring a mandatory value for End-Point Info.

Were there any recent changes to the OFSC Email configuration?

If the End-Point Info field is now required, what values should be entered? Previously, when OFSC Email was selected as the Name, I cannot recall there was the End-Point Info fields as it saved successfully as shown below under
