Appian DocuSign Connected System Token No Refreshing

I created a DocuSign Connected System and authenticated using Authorize Code Grant.

I was able to authenticate successfully and call APIs as well, but after 8 hours when the token expired I did not find any way to refresh it.

I had to manually authenticate again. Please help me on how to refresh token once its expired without manually authenticating it again and again.
