So I work for an organization in a large company (for a little bit over a year) and recently the scrum master of our team has been promoted to manager so he is now a manager. This led to an open role inside our team of scrum master and one of my coworkers and I were the primary options for it.
I am in charge of another 2 roles inside the team while the other person isn't in charge of any (apart from another third person whom I don't know why he wasn't an option for the role) and I have also been assigned this role. While normally I wouldn't mind getting more responsibilities, I mind in this case as this is not the path which I want my career to follow.
I am personally someone that do not like organizing things as I can barely organize myself. I also do not know anything about scrum more than what I have seen in the past year.
My question is, how (if I should) can I tell my manager that this is not the career that I would like to follow?
