25R2 Cannot access ARTaxTran DAC even though user has permissions

In 25R2 I have an admin user account that has access to the AR Invoices and Memos, yet when I try to access the odata for the DAC, I get a 403 after entering my credentials.

The same user works on other DAC level odata endpoints. I also tried the odata4 url string:

I assume I’m missing something simple :-)
