Adobe Target - List all Activities API Sorting not working

How to do soring based on ascending or descending order for list activities api in Target?

Soring by : name
https://mc.adobe.io/TENANT_ID/target/activities?limit=25&offset=0&state=deactivated&type=ab&sortBy=name&sortOrder=name:desc

https://mc.adobe.io/TENANT_ID/target/activities?limit=25&offset=0&state=deactivated&type=ab&sortOrder=name:desc

Soring by : modifiedAt

https://mc.adobe.io/TENANT_ID/target/activities?limit=25&offset=0&state=deactivated&type=xt&sortBy=modifiedAt&sortOrder=modifiedAt:desc

I tried several combinations but sorting is not working as expected.

I followed the documentation but nothing mentioned about the sorting parameter.
