Relevant data in the tutorial was not found

[Rwtkc]

In the text section it is mentioned that the test data is an rds file named ('seurat_with_time.rds') but in the code it is mentioned that readRDS('CM_seurat_with_time.rds'), is there only a naming difference between these two files , or are they two completely different files, please give a clarification, thanks, also I noticed that in the beginning of the tutorial it is mentioned that Test data used in the following steps can be downloaded from google drive. this google drive requires access rights. Please solve my problem, thanks
