If I have this advancement, who will it be granted to?

{   "criteria": {     "requirement": {       "trigger": "minecraft:player_killed_entity",       "conditions": {         "player": [           {             "condition": "minecraft:entity_properties",             "entity": "killer_player",             "predicate": {               "team": "bounty_hunter"             }           }         ],         "entity": [           {             "condition": "minecraft:entity_properties",             "entity": "this",             "predicate": {               "type": "minecraft:player",               "team": "bounty_target"             }           }         ]       }     }   } }
I'm wondering because I can't test it myself because I don't have anyone to get on my server with me lol, does the killer or the victim get the advancement?
