Hello. made my very first step in using matrix-nio this week end.
I may need a push in the right direction.
I have nested spaces with a room at the end

SpaceA 
    SpaceB 
        Room1

i want to display spaces and room in the right order
I'm using space_get_hierarchy for each room my account see, to get room and spaces, but they are sent to my client in this order : SpaceB[has child room Room1], SpaceA[Has child space SpaceB]

Do i use the right function to try to get space and rooms in order to display them?
