Hello Abhishek,
In the META response you can add new meta data key to be returned -> isMeta=true
and then in the VSM/ VS Image Response Selection step you can add an assertion to verify if you got the value isMeta=true.
You can change what will be the next step when it finds the string "isMeta".
Hope it helps, if not, please, provide more details on what you need to accomplish.
Thank you,
Heloisa
