[1.16.5] Getting POI for not generated chunks

[DavidQF555]

For this teleporter, I'm trying to make a portal that links to another dimension that has naturally spawning portals as features, and I want it to teleport the player into one of the portals of the other dimension, if possible, instead of creating a new one. However, it cannot seem to find any POIs in the target dimension because they aren't generated yet, and I don't think PointOfInterestManager.ensureLoadedAndValid() really generates my feature. I was wondering how I could find the POI for chunks that haven't been generated yet.

I was able to trace it to PointOfInterestManager.getOrLoad() being all empty optionals after calling from getInChunk(). I thought that PointOfInterestManager.ensureLoadedAndValid() would load all the chunks that I'm searching, but apparently not.
