I wan't to use WPMUDEV Chat plugin to provide chat support

I want to use WPMUDEV Chat plugin to provide chat support to potential customers landing on my site.

I don't want them to register on my site to user chat support.

I am so far unable to find any option in WPMUDEV Chat plugin to allow guest to use this without registration / login.

Could you please let me know how to do it?
If it is not possible, how can I add its feature request?

Thanks
