Chests with the minecraft:chests/trial_chambers/reward loot table (which can be located in minecraft:trial_chambers/hallway/rubble) can contain unique item of vaults, such as the Bolt armor trim, the Precipice music disc and the Guster banner pattern.

   /give @s chest[container_loot={loot_table:"chests/trial_chambers/reward",seed:11}]
   /give @s chest[container_loot={loot_table:"chests/trial_chambers/reward",seed:15}]

2. Place down and open the chests

Observed result:
There is loot that is supposed to be exclusive to vaults in the chests.

Expected result:
