Retrieving clientMetadata information trough dynamic approver trigger

You can use the {{$.trigger.accessRequestId}} to make an HTTP request to one or both of the following APIs:

For example: GET /v2025/account-activities/{{$.trigger.accessRequestId}}.
This will provide the clientMetadata of the request level.

For example: GET /v2025/access-request-status?filters=accessRequestId eq "{{$.trigger.accessRequestId}}". This will provide the clientMetadata at the requested item level.
