I have a form (“Social Test”) than on submission it creates a SharePoint item in list (“SocialList”). The SharePoint is then used to populate a planner task in a planner (“SocialPlanner”).
The Planner task is moved around in various buckets and has labels assigned by staff.

Once the task has been actioned by staff, I’d like the labels that are on each task to be inputted back to the corresponding SharePoint List item. I created a new flow to try do this (see screen grab)...

I have followed these few instructions / and these to get this flow to update the SP list, but I can only add a new item and I loose all the original details that were submitted to the SP list via the form.
See Screengrab below of the original items (1-4) and then the new items with the labels, but no data is taken into Type or Email.

How do I identify the original SP item (items 1-4 in screengrab above), and update the specific “LabelTag” column in SP, with the labels assigned in Planner?
