Hello @Phani Pasupulet
you can add the condition as assignment group changes in bR, still it is not going to give the value on change time.
If you want email id of caller on change time then you should have to use client script. using BR is not possible to get the value on change time. you have to use getReference or scratchpad or script include to get the email id of caller on change time.
Please mark my answer helpful if you find this useful.
Thank you,
Praneeth.
