URGENT: Edit Region Widget Via API


I need urgent assistance please as the deadline for completing the project I am working on is fast approaching

I am working on a layout that has two regions. One is called the “mainRegion” and the other is called “logoRegion”. I have so far been able to target the “logoRegion” and assign image widgets to that region using the /playlist/library/assign/{playlistId} call. I want to be able to edit the alignment and duration of the image i assigned to the “logoRegion”. Which call will be appropriate? I went through the API documentation and did not find a put call for image widgets.
