On Phantombuster, each agent receives a JSON object as an argument, which can be set each time they are launched.
/*Bot launched with argument:

"name": "nick",
"age": 2
}

const arg = buster.argument
console.log("The name is", arg.name, "and the age is", arg.age)
//This will print "The name is nick and the age is 2"
