It's missing from the documentation as of 19th Feb 2019, but the chat command is /sign.

I set "Chute: true" in the setting of the BOT of each monument.
Then the BOT disappeared before reaching the ground.
This remained in the log.
"Failed to spawn assets/prefabs/npc/murderer/murderer.prefab on a valid navmesh."
