Hi everyone,
I have a custom requirement where the author wants to activate through workflow more than one asset using search filter option. a button needs to be available to start a workflow but i'm not able to find whether I need to overlay from libs or create a custom js.

I tried to find documentation but there is not any reference. Could you please help guide me in how to accomplish this requirement?.
EDIT: a similar thread had been created with not response. Has someone created something similar?
