@Shwetanana Shweta Thanks for reaching out. Yes, your understating is correct that the logic app ICM connector is depreciated now. ITSM connector lets you send alerts to an external ticketing system such as ServiceNow and for more details you can refer to this document.
A viable alternative/workaround would be creating a custom connector that interfaces with the ICM's REST API.
In case if you don't want to create the custom connector then you can create a function to call ICM endpoint to do ICM operations and let logic app calls this function.
