2019 rear shock/strut replacement

I am helping my daughter with a suspension refresh. I was able to replace the front struts with only minor swearing and cursing. Remove all the cowl stuff, Wth? However the rears through me for a loop. How do you get to the lower mounting nut with enough torque to remove or correctly torque it back on?

 

I found this from @Mendel Leisk https://attachments.priuschat.com/attachment-files/2021/08/211165_4th_gen_Suspension_-_Rear.pdf. It is great but for the life of me I do not see steps to remove the shock. From attempting to do this it feels like a good portion of the suspension needs to come out?
