In the trial run mode add the list of 10 matched entities even if the total number is large
In the Trial Run mode it is very useful to see example entities when their number is low (I think 10 or so). However, when the number of matched entities is large, it does not display any matched entities, just the total number:

When setting up new alerts it is useful to see example values for the entities and therefore it would be nice to still display e.g. 10 first entities.
the limit is imposed in the backend, currently set to 25. In other words, if 25 entities or more match, the backend only provides a count, not a listing.
Not sure what the implications of attaching the first 10 matched entities onto the response would be. Maybe @vibhory2j can take a look when he has time.
