Hello @AP_10343008 ,
I have been looking at this issue.  When you define a service which creates the data for the grid, you need to have an input parameter of type "Query".  You can use the Browser developer tools to view and capture the structure which is passed.

This example has an empty value field. If you provided a similar structure as an input parameter to you service in composer it would return the rows which have an empty value in the "office" column.  
What I don't know is how to get the Chip Data Filter Widget to generate this structure. 
I will post an update when I have completed my research.

@AP_10343008 ,  I have tried a few different approaches to this question. I believe that currently it is not possible.
