On one of my OPS there is something called Tribunal, it has very vague instructions on how to use or if I can even use it. Says it teleports fleet from outer space to the tribunal, costing 1 million vespene, so I placed a fleet in orbit and https://prnt.sc/p091xk . Then I tried going to the tribunal page on the OPS https://prnt.sc/p091cx where it shows me the description, with wrong levels of building https://prnt.sc/p090kv, but also like it doesn't exist or I can not use. Also switching to another planet, without the tribunal https://prnt.sc/p093cb shows me the exact same page, not with an error saying that there is nothing there to teleport with.

The summon by the Tribunal is made in the Fleet menu.
