forkJoin fails when given a dictionary/object despite the RxJS documentation saying it can handle that

[Naram Qashat]

So, if you look at the first example for forkJoin at https://rxjs.dev/api/index/function/forkJoin it mentions using a dictionary of observable inputs. If I try to use that forkJoin example with RxViz, though, it shows a failed Observable with the tooltip being You provided an invalid object where a stream was expected. You can provide an Observable, Promise, Array or Iterable.. It would be nice if RxViz could support passing a dictionary into forkJoin (or maybe any other functions that also could take a dictionary, but I don't know what others are like that offhand).
