What I'm trying to achieve is when an item is created in a SharePoint Online list located in one site collection, to create that very same item in another SharePoint Online list located in another site collection having the same field values(that I managed to achieve). Then, when that item(the created from the first list one) is modified in the second list that took the entry from the first list, the field values that were updated in the second list to be updated in the corresponding fields for that very same entry in the first list. Any ideas how to achieve the second part? I used Microsoft Flow to achieve the first part. Pic of the flow that works only from list1 to list2:
