guys I have another questions, I was looking for a solution long time already, what if I have a observable called ImustbefinishedandcalledonlyOnce and it fetches some initial backend data, each other backend call must wait for ImustbefinishedandcalledonlyOnce to complete before they proceed
my questions is: is there a way to attach a running observable to some observable chain?
something like this

getRunningInitialObservable().flatmap(someOtherObservable).subscribe()
