I want to show a dynamic message how I can do this using message master:

Message Template:

Emp id {{loginId}} has already created a lead for the same customer. Do you still want to proceed with new lead creation?

Can we use any JSON path between {{ }} or there are any fixed keywords? If these are fixed keywords, can we gest a list of those?
