H1B First time Vs H1B Renewal

Hello,
I’ve booked for a Dropbox appointment for September 2022. This is my first time H1B stamping.
However, I am doubtful if I booked for first time appointment or renewal appointment.
Is there any way I can check what my appointment type is?

I dont think they will show whether first time or renewal. All appointments are simple visa stamping in the category you are applying.
