How do I use timestamp or similar to add a value to firebase every 24 h?

Found this post stackoverflow.com/questions/53652196/how-to-update-a-value-every-time-in-the-period-of-24-hour-in-firebase-android ,

im using the addon collection with firebase for C3 runtime, now on c2 i remember how i did this, i have a hard time getting this to work on C3 tho.

Every for example 24 hours i want key TEST value to add with 1.

Does anyone have any tips on this?

You could try using a firebase cloud function with a setTimeout of a day then the function call itself again. don't exactly know how to call the cloud function from construct tho.
