For the moment I saw the presenter and guest roles in the examples.
There's any more kind?¿ It's posible extend the default roles?¿
Role can be defined, currently in MCU we provide 4 roles: admin. presenter, viewer, no_text_viewer. You can define a new role and customize authorities for the role in MCU, before v3.4 Release, role definition configuration is in portal/portal.toml, in v3.4 Release, it is in session_agent/agent.toml
