Hey Gokul,
To achieve your requirement,
 you can go through my blog and in that blog,

https://medium.com/@rishabh.shandilya/create-your-own-way-of-filter-by-npe-non-persistant-entity-and-microflow-4ffd11e52fb0

and when you make the NPE, just make its association(1-*) with the entity which you want to filter.
 And the rest is the same.

Hope it helps!
