Model Driven In-App Notification

Hi, I am using Power Automate Flow to send In-App notifications to our users. I have implemented this by creating a new record in notification table in CDS(Screenshot1). we are facing an issue while trying to pass custom data while creating new record(screenshot1).Custom data which I am trying to pass is in (Screenshot2) and in the below link also. Can anyone please help me to map this data into Power automate flow Data Column. Thank You.
