You can join their discord channel and then find the Exoworlds section. As far as adding it to your discord, thats above my head.
When in the exoworld channel…
!exo (gives a list of current exoworlds)
!planet planetname (gives a list of the resources available on that planet … works for perm worlds too)
!res resourcename (outputs the top 10 planets, perm or exo, with that resource and the amount)
