Where has the drawing canvas gone ?

[Interlectualpropertie]

I was using the supermemory drawing canvas for work projects, at the start of November, in the new version I cant find it anymore, is there anyway to access the sides or if they have not been saved copy your code for the drawing space, cause that one was really helpful. By the way I could not find a support hotline or channel so here we go, thanks in advance.
