LWC Component Override for Messaging Element

I’m working on overriding the standard Messaging element in OmniScript using a custom LWC that extends OmniscriptAtomicElement via LWC Component Override.  

The UI renders fine, but I’m running into a key issue: I need to conditionally show or hide the message based on a formula field in the OmniScript data JSON (e.g., IsAvailable). This formula evaluates to true/false based on field selections in the same step. However, inside my LWC, this.omniJsonData always returns undefined, so I can’t access the value.

Here’s what I’ve tried so far:

• I’ve extended from OmniscriptAtomicElement as required for element overrides.
• I attempted to mix in OmniscriptBaseMixin to access OmniScript’s reactive props like omniJsonData, omniJsonDef, etc., but that didn’t work either (it throws errors or breaks the override structure).
• I also verified that the formula field is part of the current OmniScript data node and accessible if I preview the OmniScript.
• I even tried putting the omniDataJson in connectedCallback() and stateRefresh() but both still result in undefined data.

My main issue is that I don't know how to pass the data from the Omniscript to the override LWC to do validation checks or post processing logic.
