Is it possible to schedule the background task to run every hour and (conditionally) make a call?

Hi,

I am looking into making an app to manage rotating phone redirects across the team (support phone).
As this is a real phone number, we have to do that using the phone with that SIM card and then make a #21#... “call” which enables redirection to a number.

Is it possible to do this with Expo?
I have found an information about Background Tasks, but I cannot find anything about how often they run/can run etc which is crucial here.
