Knowing the referee lab who approved you / payment for application

Hello everyone, we’re new to this site. We just want to ask, can we know specifically the referee lab who have approved us? We think it might be helpful for us to trace and establish connections with them if we know who approved us. We received a notification that one of our referee labs have approved us already. However, we don’t know who they are among the three.

Also, is there a payment for our application in the organization after the approval? if there is, how much will it be?

Thank you so much for your attention.
