How do I get level 82 Expedition Logbooks?

I am currently in the process of trying to get level 82 items for crafting.
I know the ways of getting 82 maps (tier 16 + Irradiated + sometimes Cleansed +1), but I have been told I can get level 82 Expeditions / Expedition Logbooks without level 82 maps.

Can someone plesae tell me what I need to do.

level 82 Expeditions events on a map should be the same process as other maps.

Level 82 Expedition Logbook you need a level 80 logbook (probably 8/8 on the tree too, didnt test it tbh).
