Sorry, confused with another area in the trial where there is a tiny button seemingly blocking a door, forcing to use teleport waypoint.
For this, I recall I did like you: used tactical retreat then teleported to the invisible waypoint. I think, you can also get there through a astarte mirror (not sure).
Design level wise it seems strange but take into account that role playing wise, the temple was not initially in this ruin state.
