lv_group_focus_obj equivalent missing? How do you focus an object?

[riaancillie]

I can't find the mp equivalent of function lv_group_focus_obj
lv.group_t doesn't have a method called focus_obj nor can I find anything related to forcing focus in lv.obj

lv.group_t.
focus_prev set_refocus_policy get_edge_cb
get_focused get_editing remove_all_objs
set_wrap send_data focus_freeze set_default
add_obj set_editing set_focus_cb get_obj_count
get_wrap get_focus_cb set_edge_cb delete
focus_next

What is the correct way to set the focused object in a lv.group_t?
