How to get all keys from a datastore?

I am debugging a gamepass issue and part of it requires me iterating through the datastore and printing out the whole data store to see every player key.

GamepassDataStore:GetAsync(player.UserID) -- this will for sure get the result

But I have to do something like this which is surely silly. I know for a fact that this isn’t right:

for i=1, howevermanyrobloxplayers do
    print(GamepassDataStore:GetAsync(i))
end

I saw some posts saying retrieving key is impossible. If so, how is DataStore Editor - Roblox possible? If you know how datastore editor works, feel free to tell me, I know how to make a plugin and I don’t want to spend 150 robux.
