API query format to only select specific records meeting the criteria - Additional filter criteria in Module "Watch a record"

I am working on configuring module in Fusion -"Watch a record", want to add & use optional filter for filtering only specific records meeting the criteria using API query. Tried adding API query but receiving error - "The operation failed with an error. [422] APIModel V17_0 does not support field property (Task)".

Want to check what API Query format is acceptable or should we use for this module, will appreciate any example sharing.
