How do I add participant to a new appointment using SoProtocol?

Im trying to open a new appointment dialog, with a specific set of participants, using a button.

Is this possible using soprotocol? Or maybe crmscript that redirect to some calcalulated soprotocol expression.

I have looked through the documentation, but the closest I can get to add anything is using &groupview=true.

https://docs.superoffice.com/en/ui/soprotocol/create-appointment.html

Ideally I would like to add a set of emails, not necessarely in SuperOffice. But if needed, a set of persons would do the trick as well.
