Instagram post should be uploaded to GMB updates

I am trying to create a workflow in which when I post image on instagram account the post is added to update section of a Google Business Profile(Google my business)
So instead of manually clicking on add update option(highlighted below) I want it to be done automatically
I mean the option below

Which option from dropdown action event do I have to select in Google Business?
Or do I have to do something else?

Currently, we don't have any action event available for your specific use case where the images could be updated. If you would like this action event to be added to the GMB action application in Pabbly Connect, you can submit your request on our dedicated platform: https://pabbly.featureos.app/b/Integration-Request

Our integrations team will review your request, and if feasible, add the desired action event to GMB.
