Hi.
That is currently not possible, as there is no certificate in database until the user issues it, so the function returning the data in Joomdle cannot use it.
In other words, Joomdle will only show already issued certificates.
If I understand you correctly, you want to show also the non-issued but available certificates, so the user would issue it directly by clicking on the certificate link in Joomdle module/view.
To do that, things would need to be done differently: instead of checking certificates issued table, it would need to get all course certificates for all courses where the user is enroled, and then check them all to see if they are available for the user, returning only those.
