Yes. In your channel admin (/channel/<slug>/admin), open the Staff tab and give each person only what they need:
- Edit Overlays — use the overlay editor for this channel
- Manage Settings — branding, colours, logos, social accounts
- Manage Sponsors — sponsors, brands, and commercials
- Manage League Claims — request to broadcast leagues
- Manage Staff — add and remove other staff (only the owner can grant this)
Permissions are enforced on the server. Two things stay owner-only: publishing an overlay to the live channel, and listing a theme on the marketplace. The owner can't be removed from the staff list — ownership has to be transferred instead.
