Seems there is a bug when u click it and drop it asap u can reuse it. But iffy but i got it too work 2-3 times was in a party with other guy that spammed it all time
found YT link Apex Legends INFINITE loot drops glitch LifeLine ONLY - YouTube
Tested it more u can actully use w/e item that has charge time like health kit or shield. Like u just need one phoenix kit u can dupe it.
