Freshservice Filter API to get value from dropdown(data source)

Freshservice Filter API has a limitation where it only supports custom dropdown fields of type “Dropdown” if the dropdown itself is the data source. Unfortunately, this functionality does not work as expected in the filter API.

I was wondering if there’s another way to filter tickets based on a dropdown field using its data source. Currently, as a workaround, we’re updating the same value in a single text field whenever a ticket is created or updated.
