Hello Candace - This is actually by design.

Restricted access to Business Central as delegated administrator
When you sign in to your customers' Business Central as the delegated administrator from the Business Central administration center, you have access to all areas of their Business Central. However, because you are not registered as a regular user, there are certain tasks that you cannot do.
The following tasks are not available to the delegated administrator:
Set up jobs to run as scheduled tasks in the job queue
Use the Edit in Excel action or interact with Business Central data in Excel using the Business Central add-in for Excel.
You can still use the Open in Excel action to view data in Excel.
Use the Invite External Accountant assisted setup guide
Instead, you can add the external user in the Azure portal and assign this user the External Accountant license.
Change the experience to Premium
Use the Cloud Migration Setup assisted setup guide to migrate data from Business Central on-premises to Business Central online
Instead, a user who is assigned the SUPER permission set in Business Central can run the assisted setup guide.
Access a web service by using a Web Service Access key.
