There are a few ways you could support the activity!
If you need to the be the one to create, manage and control all aspects of the activity, it could be created as a Project Patrol with you as the organiser. This would be done through the Programming functionality when creating an activity.
If you are going to support the activity while it is running, but don’t need to be in control of the activity in the system then you could have the activity shared with you.
If you’re being involved to teach a specific skill or activity in some I-statements, then you could be marked as a verifier through the Outdoor Adventure Skills functionality.
