How can I change the owner of a group?

There can be more than one owner of a group, as there can be more than one administrator of a group. So, the person that creates the group, doesn’t need to keep being the owner of the group. As you can’t change the roles of your own profile, you will need to add at least another member as the owner and administrator, where after the person can sign in and remove the first one as member of the group.
