Test Aadhar, eMudra, 3rd party DSCs on trial Sign API

Is it possible to test out Aadhar eSign, eMudra eSign, eMudra eStamp etc. on Zoho Sign API while using the Enterprise trial plan, without buying any credits?

Or do we still have to buy credits on trial plan to test the above via API?

I got an error when testing Aadhar eSign via dashboard, saying I don't have enough credits.
