How to create a second spark chat window in the same PC?

I’m new to Openfire and experimenting with the Spark client on my laptop. Is there a way to open a second Spark session? I’d like to have two Spark sessions with two separate logins on the same device and just chat back and forth, but when I try to create a second session Windows 10 just brings the first session into focus?

Hi
May be use Sandboxie?
I think it resolve your ask.

You can create another Windows user and run Spark via Run as and select that other user. This way this other user will have a completely separate profile in C:\Users\User2\AppData\Roaming\Spark. Or you can create copies of Spark.exe in Program Files\Spark and run them separately.
