Alert Composer - Unable to select attribute when insert expression

Summary:

Hi All,

We are trying to create a custom alert for Journey Assigned Alert (Code:ORA_CHK_CHECKLIST_INITIATED) but there is no attribute we can select when insert the expression on content.

Just wanted to check if there is any security we have to grant to our implementer account. As of now, we have granted the job role "Human Capital Management Integration Specialist" to our accounts and ensured that our implementer account are all having the functional priviillage "PER_REST_SERVICE_ACCESS_WORKERS_PRIV".

Expected Results:
