How to apply to main store?

Hey,

my app currently goes through App Lab review and I am already looking forward seeing it on the main store 😉
I wanted to ask how does the graduation from App Lab to the main store process look like?
Is there any separate submission process for the Main Lab, should I get in touch with the support if I would like to apply to the main store?
I would highly appreciate it if someone who went through the process recently could chime in and describe their experience- thanks!
