const functions = require("firebase-functions");



exports.impersonateMakeUpperCase = functions.database
.ref('Searching for match/level')
.onCreate((snapshot, context) => {
    
    /// get all the children keys under 'level'

 });

I'm trying to make a function, returning an array of all the children keys under "Searching for match/level" every time a time child is added to there, any solution?
