The word facilitator comes from the French word "facile": easy. The role of the facilitator is to make things easier.
Having a facilitator in the team will make things easier.
Make workflow visible, e.g. with a cycle board
Make sure the team meets
Make sure you have notes of the meeting
Exchange information with the team - ask questions, follow up
If you're very actively involved with operational topics you most likely will neglect your facilitation role
Don't push your own agenda!
