Hello @Hiewwaiy . At the moment you can't transfer the role of group Admin. However, with the current features we offer, that should not be too much of a bother. Indeed the group admin is just the person who created the group. But there are no permissions or notifications linked to that role. 

When we will add extra features to the group like notification when and end-users ask to join that group, then the group admin role will have more sense and we will consider allowing to change the group admin. 

I hope this helps
