How to reuse a project

I am going through Video Demo for Libraries under How to reuse parts of a project? under RPA Developer Foundation certification.
I was trying to replicate the demo and i am stuck at Navigate_to_Home_page.xaml and Download_all_work_items.xaml files. When i am trying to capture the element using indicate element, i am not able to selec tthe home button in Navigate_to_Home_page.xaml in Chrome browser and similarly the indicate element is not able to capture the work items table. Checked in the demo zip file provided but not able to follow the same in my practice.

Is anyone else facing the same issue? Also need help on the same.
