Suggestion

The API integration allows for filtering based on specific values assigned to specific keys - it would be nice to expand that sort of functionality to other integrations that include key/value pairs within extra properties or other mapped fields. In this case - it would be for the 'Details' map for the Cloudwatch Events integration.

Workaround

It is possible to achieve something similar to this as the map of key/value pairs is available as a string in the mapped 'details' field, so filtering on that field in the format of:

Details - Contains - 'key:value' 

will work instead of having a dedicated field for the key and value.
