Has anyone successfully created and published a Miro Marketplace app?

Morning! I've got several Miro apps that I've built and people use across our company, but I'd like to get these published formally - especially due to the apparent marketplace benefits you get for publishing an app (like business license seats, etc.).

A few questions:

1. Has anyone successfully gone through this process?
2. Do you HAVE to follow the mirotone style guide in order for the app to be approved?
3. Anything else to know that causing sticking points in the process?

Thank you so much!
