There is a video on youtube. Have you tries pegging the inner tent out lightly and lining all the poles out. Someone will be able to help you as in longest poles go in the longest area. Are the poles colour coded on the ends? If so you can look at the ends of the sleeves and you may find a strip of cotton co ordinating to the pole.
I know its not much help until someone with one answers.
Having a look around FB market place some one is selling similar. It does look like the poles and sleeves are colour coded
Sunny day, a back garden, help from friends, keen sense of humour. There are only so many permutations for putting a tent up. Once it’s correctly up, use coloured tape or nail varnish to mark any pairs that connect. Take photos. And sleep in it that night (maybe without the friends). Then pack it away logically.
As has been said, it’s very likely there’s something on YouTube.
