You are fortunate to have an experienced team that has worked together for more than a year and is familiar with the project work. What would you expect as your main activity managing this team?

Remove obstacles so they can do their work.

Explanation:

In fact you are very lucky to have an efficient team working for you that has been working together for a relatively long period of time. Since they are capable of performing their work properly and apparently do not need any additional guidance, the best thing you can do is eliminate any obstacles that can interfere with their work. At this point, you can lead them, but they will do their job very well even without you. So the best way you can help them is by removing problems out of their way so they can do their job efficiently.
